I've been keeping this project semi-secret for about a month now, but here it is!

Titanium is a multiplatform IDE written in C++ using Qt, that will help develop programs for the TI-84+CE. When finished, it will have ASM, C, and TI-BASIC support.
The name is Titanium after the element with the symbol TI.

Features:

Dark, photoshop-esque interface
Compile to ez80 assembly, decompile .8xp files
Compile to C (using the CE SDK)
Compile to TI-BASIC, edit TI-BASIC programs.
Multiple files at once
Cross platform compatible
Sprite Conversion
ZIP file import
Syntax Highlighting/Autocomplete
More to come!

File formats are .tIDE, which are basically .xml's (but I don't want people messing with them). In its appdata folder, it stores a file called quit.tiQ, which stores the previous project so it can be retrieved, and it stores a session file, for editing outside a project (a temporary project, but that's only so the session can still be intact on restart).
The editor stores a cached version of text inside its project files, so you can have "unsaved" text persist throughout sessions and not have to overwrite the original file to quit the program. You can, of course, use the save button to actually overwrite the file when you wish to.

I'm not going to link the code (or a compiled version), since the program is not very feature complete, and basic things aren't implemented (I wouldn't want someone to put in the effort to make a pull request, and have to reject it because it doesn't meet my vision for the basics of the program )

Anyway, what do you think? Would you use something like this? If not, what would you want to make it more useful?
Questions, comments, suggestions, and feature requests below!

Special thanks to Mateo for helping out with some bugs and for being really helpful!

I like it.

I like it even more.

One feature that I have always wanted to see implemented into an IDE like this is the opening of zip files, and putting all of its contents into a project (except for subfolders and non-compatible files, of course). One thing I like to do is download other peoples programs to study and learn from their code, but extracting and then importing the files into an IDE is just an annoying process.
If you could implement a feature like this, I would be very happy.

I second this. It would definitely make my life easier.

Also, what does this offer that is better than TI Connect CE for basic programmers? As of now, that is my main program, but if this offers syntax highlighting or auto complete I would definitely switch to this.

Hmm... I never thought about that. I assume it would have xLIBCE support and such included, but I will officially add syntax highlighting / auto complete to the feature request list, along with opening zips.

Edit: I was thinking about adding a Scratch-like editor to Titanium that lets new coders drag and drop, and then see the code they are creating using a toggle... This would allow more coders to create cool things for the CE, and still make engaging and fun contributions to the archives all while learning how to code! I think this would be a really cool feature (and of course, it would be C, not assembly or TI-Basic).

I would think that would be more effective (and easier to implement) as TI-BASIC rather than C. Also, that's far beyond the original scope of this project, but I think it would certainly be great.

Sheesh, why not make the IDE write all the entire program for you then, since you seem to be making this a super-IDE? XD

This does look pretty neat, though.
