Speacking of many options. Has anyone used ImageJ? It's a Java image manipulation tool mainly for medical and other science related imagery. Anyway, it has a really useful little gadget that you can open and quickly search for all (I think) available commands, anything menu related gets added there.
This feature I think is missing from both GIMP and G'Mic, both of them have too many menus, commands and stuff, so I think both should benefit from such a thing. ImageJ is open source, so those who have an interest may have a look at how they solved it.
This is too stupid!. I have to obfuscate the friggin' uri?! http 'colon-slash-slah' rsb'dot'info'dot'nih'dot'gov'slash'ij
So, now you have to figure it out.
