What I would really like to have, is the ability to display a JPG file immediately after launching a program from Dmenu. The picture would be displayed until I press any button, in which case the picture would disappear and the program would launch as normal.
This would be useful to create and provide instruction cards for all the different games and programs that you would want to in Dingux.
Off the top of my head, the worst offender is Another World (RAW emulator) where I can never correctly remember what the "Load State" button combination is before I accidentally overrite it. Then its back to trying to get past the copyright protection all over again.
I personally know very little about Dingux, Dmenu, or how to do what I am proposing even in the slightest, but if anyone out there is more knowledgable than I would like to flesh out some of the possibilities, that would be great. It would really increase the usability of Dingux for infrequent users (me) or new users (people I show it off to) a whole lot.
