Originality 9/10 - its Windows, as the name shows

Ease of use 8/10 - took me a while to find out how to right click (ALPHA)

Speed 9/10 - it takes a while after program execution to return to Doors

Functions 10/10 - Nested folders, icons, alpha-clicking

GUI 8/10 - You lose your folder structure if your RAM crashes

Features 10/10 - I like the meters - although I don't believe the battery one works

Compatability 10/10 - works.

Usefulness 9/10 - takes a while to get used to after having MirageOS for 3 years

Size 8/10 - twice as big as MirageOS was.

Program execution 10/10 - runs all my games, but so did MirageOS

Speed: 5/10

The scrolling is a nice speed, but some menu and folder operations are a little slow. Moreover, when I run programs using Doors, the programs themselves are actually slower. I noticed that playing Falldown- it was insanely easy, even on the fast speed. Maybe it's an inheritent problem with operating systems, but programs do slow down!

Ease of Use: 9.5/10

Usability is the most important thing in any OS, and this one nails it. Any one that has touched a computer in the last 20 yeas will understand it's Windows/Mac like interface easily. However, crashes still happen, and this program isn't as reliable as MirageOS.

Functions: 9/10

I really like the idea of having an icon for each of my programs, even if it will take me a while to figure out how to make them. The folder options are sufficient. What's annoying is that every program you have shows up on Doors the first time you run it.

Overall: 8/10

This version of Doors CS is quite a lot better than other shells I have used over the years. The mouse goes fast, the scrolling works well, and I like being able to make custom icons for my programmes. A while ago, I got Doors 4,9 to see how good it was. It did turn out to be quite buggy, unlike this version. It has not crashed my ti 84+ SE once yet.

For a rating, I would give it the following:

Speed: 9/10 Adjusting the settings is quite slow.

Compatibility: 5/10 This is NOT compatible with the Nspire.

Usefulness: 10/10 I always use Doors to rename and lock programmes.

GUI:8/10: You'll lose your folders if your RAM crashes.

Programme Execution: 10/10 Runs almost all programmes requiring a shell.

A while ago, i tried out Doors 4.9. I was amused by the interface and loved the mouse, but there was thing. It was so darn slow and buggy! Over the summer, I saw Doors 6.1 CS had came out so I thought "Eh, why not." Having used it now for 4 months, here's my review.

Graphics: 10/10

The graphics are great! Much better then Ion's spartan interface and MirageOS's barely graphical one. The Icons for programs were great too.

Speed: 9/10

The mouse moved fluidly. The only problem was that the scrolling is slow.

Functinality: 10/10

Icons, numerous file types supported, Easy to use settings and commands, this OS has it all. You can do all standard memory function beside Groups and edit Basic Programs.

Debugged: 9/10

There's a few bugs in there, but none to serious.

Origonality: 8/10

Mouse based systems like this have been made before, but none are as good as this.

Over All: 9/10

This shell is absolutely amazing. It features support for both Ion and MirageOS programs, it has a fully functional GUI API for Assembly programs, and a built in, multi-calc networking protocol, also for assembly programmers.

It also has features for Basic programmers, such as the ability to hide sub routines from the shell, and to automatically unarchive them at runtime so you dont have to take up your precious RAM. It also has intelligent writeback to save wear and tear on your archive: it only writes-back if changes to the program have actually been made.

For supreme organization, it allows you to create nested folders, and auto-sorts your programs at start up far faster than MOS does.

Finally it has the ability to run shell extensions, small programs which add on to the capabilities of the shell.

This is an awesome OS! I, personally, think it's better than MirageOS. It has all the features Mirage has and more. There are a couple bugs, but they can be easily fixed. It's pretty fast, and looks better, too. If you have a choice between any other organizer and this, get this.

DoorsCS is a fantastic shell. It has a very intuitive interface that is extremely simple to navigate. It also includes many features that make it worthwhile. You can make Basic programs automatically unarchive required subroutines, and the ASM libraries it houses make stuff like text editors less than 1000 bytes, yet the editor has a very graphical interface.

The only complaint I have is that hiding programs using DCS only hides it from DCS, not the edit menu, and the token used for this messes up Ans if you were to run the program normally.

This app version of DoorsCS is MUCH better and more stable than the previous assembly versions. Although it has already crashed my calculator twice, it certainly didn't break down right at the beginning as it used to. The program is very easy to operate, due to its icon and mouse design.

However, the battery and RAM meter did not work on my TI-84+. It does not have a hide feature, which is a problem because the interface shows certain programs that can not be executed. The animation, although unbelievably smooth, is a little slow. And you still have to garbage collect.
