type an expression like "i(2i-3)" and have "2-3i" show up

"-2-3i" *
Anyway this sounds pretty cool. I have yet to check it out.

Two updates on the image editor:

• Made grayscale conversion of color images more accurate. Specifically, it now works with WabbitEmu-style green palettes.
• Export images as PNG, GIF, and JPG files!

Now IES has image conversion working both ways—TI pictures to computer images, and computer images to TI pictures.

If all you want to do is convert an image from one form to another, it's really easy with IES—just drag-and-drop your file, and press either Build to convert to a TI picture variable or Export to convert to a standard computer image.

It also works as a quick way to convert a color image into a calculator palette, since all color images are parsed into two-, three-, and four-level grayscale (greenscale?) when you drop them into the app.

Does it also scale to large images? And greyscale 'em?

Yes, images larger than 96x64 are scaled down appropriately. All images are converted to two-, three-, and four-level grayscale—you can toggle it with the drop-down next to the image.

Think I should add another option to scale up an image when exporting to PNG/GIF/JPG. 96x64 images on a computer are tiny

And a little suggestion: maybe add as a neat little feature zstart image support?

I don't know what that format looks like, but I can certainly look into it.

Another quick update: Added that scale factor I was talking about in the previous post. Exported images can be 1x, 2x, 3x, or 4x the standard size (96x63).

So IES is now a quick tool to scale your TI images as well

Will it eventually support both TI-84+CSE image formats? (133x83 65536 color background images and 265x165 15 color+transparent ones)

Maybe someday.

I'll have to use a completely different editor system though—right now it's a giant table with a cell for every pixel (to ensure compatibility with IFE7), but a 265*165=43725-cell table might be too much

What would be nice as well is Casio PRIZM pictures support (the 8 color ones that are also transparent I think), because there is currently no way to edit them other than on the calculator, which takes an incredibly long while.

Another set of tools for PRIZM BASIC programming might be planned someday.

Another solution would be to completely drop IE7 support. After all, several people have stopped supporting anything lower than IE9.

That's probably a good idea—I'm even using an old version of the CodeMirror editor library because the newest version drops support for IFE7. Because nobody uses it (or should) anymore.

But up to this point everything on ClrHome was IFE7-friendly

Wait a sec - maybe you could merge this one with bbfier, so that also have a button to export to bb-code or to html code! (Just a thought)

It's been planned since forever, but I never got around to adding it. Keep reminding me.
