I actually have my own feature requests for PNGGauntlet, but I'd love to hear what other people want. I only occasionally get to work on PNGGauntlet, but this is what I'm looking to add/change in the future:
- Better compression using advanced PNGOUT options (esp. on grayscale)
- Possibly switch PNGOUT for ADVCOMP or some other compressor
- Write my own C++ PNG compression/recompression library and port it and a GUI to linux and MacOSX (hey, I can dream)
Happily, I can now move the following items to the "finished" pile:
- Save settings between sessions
- Red highlighting for bigger/failed files
- Getting rid of the PNGOUT output box, or at least cleaning it up, since the new version of PNGOUT dosen't print nicely.
- Cancel function
- "Clear File List" button
Check out the newest PNGGauntlet to see 'em in action!

One feature that would be great: the ability to set the priority class for the PNGOUT processes PNGGauntlet spawns, e.g. to low, but I guess also to high if anyone wanted that. This way it could run in the background and not slow down everything else on the system.

Personally, I'd really like it if PNGGauntlet would understand the following syntax (intended to launch PNGGauntlet with the given file(s) already included in the "Files to optimize" list):
PNGGauntlet.exe somefile.png
This would allow me to right-click an image file and pick "Optimize" in the context menu. A switch to tell PNGGauntlet to optimize the given files and then exit would make this feature even nicer.

Excellent suggestions. I have another: a mode where it tries compression with both NONE and MIXED filter types. Right now, paleted gets NONE and anything else gets MIXED. I've found that some images do better with another setting, and it'd be nice to have a "Brute Force x2" mode where, once the minimal colorspace has been found, you try to compress twice. For example, do what you do now, and then compress with the other setting from the destination to the destination. If worse, no changes. If better, you get a smaller file.

Examples of "bad" files: a "paint-generated" RGB file with little more than 256 colous (will get filter, it'd be better if it didn't); a pseudo-greyscale file which has 64 greys and 64 reds, will be paletted and get no filter, but it'd be better with it.

I have a useful suggestion for the PNGGauntlet GUI: The drag to window feature is convenient, but I think allowing copying of files and them pasting them into the PNGGauntlet window will be more convenient. Especially in cases where window position will make file dragging difficult. (A similar feature can be seen in Nero Burning ROM's Nero Express window, where you add files that you want burned into a CD.)

Good ideas.

I like this idea. Right-click->optimize is very convenient especially if you only want to optimize a single png file. Right now, what I do is: open the file with Irfanview and save it using the Irfanview PNGOut plugin

Hm, well if there's a PNGout plugin to IrfanView, why do you need PNGGauntlet?

Well, you can't optimize a large no. of png files easily using Irfanview. I use PNGGauntlet mainly for batch optimizing. (That's why I suggested the copy-paste into the window).

A right click-> Optimize PNG with PNGGauntlet option, will be much easier and faster than saving it with the Irfanview PNGOut plugin.
