I regret I didn't install the auto screen shot addon I have now from the beginning - maybe some day I'll reroll just to make a story or movie of the evolution from 1-80 in 80 pictures (though when I finished raf I sweared to myself I would never ever do 1-60 again)

I use:

I also takes shots of achievements, boss down, etc... (the boss down part is maybe a bit over the top as my main somehow lags during screenshots and sometimes I die at the end of boss fight because I don't move out of poison, etc... during the screenshot)
