The ability to take a screenshot directly on a device can be used for debugging and documentation, e.g. in posts to this forum. The iLiad already has fbshot (http://www.mobileread.com/forums/showthread.php?t=8626), but its recommended use is via ssh from a PC. What I am requesting is a single click way to get a screenshot. For example, on the Nokia 770 there is a combined CPU/Mem/Screenshot applet (https://garage.maemo.org/projects/load-applet/). It is always on the screen, so a screenshot is one click away. I think this would be useful enough for iRex user support that its availability should be guaranteed. So I suggest adding it to the battery status indicator. Another option might be to add it to a clock.

A simple shell script wrapper might be enough, but the "single app" nature of the iLiad would then need a delayed shot to allow you to switch back to the screen you want.

In any case, the standard way to get unique filenames is to include the date:

fbshot SS_`date +%y-%m-%d_%H:%M:%S`.png

The problem with adding new items to the tray area, is that it pushes the left bar (pen functions, etc) further to the left, and off the screen. Until iRex fixes this, I don't think that adding new applets is feasible.

The tray area problem is one reason I suggested adding this to an existing applet. For example, the battery indicator just sits there and could easily be overloaded (click on the battery applet and get a screenshot). Alternatively, a non-tray always on-screen application, such as a clock (http://www.mobileread.com/forums/showthread.php?t=13526) could add a screenshot option.
