GASP! 
this is fantastic! Thank You! Thank You! Thank You!
we chatted bout this a while back.
I'm running out of hotkeys... ...and my toolbars continue to grow all the time. So this this going to be great! I've started using AHK with #ifwinactive to send tricky hotkeys to dopus when keys are double tapped. But I digress.
Two thoughts\requests...
#1 Is there (or could there be) a way to open into customize mode on a selected item? alt + enter ot dopus own alt + click
#2 add a dedicated hotkey column that shows current hotkey if found? This kind of overlaps with the customize window, thou this does a better job finding every toolbar item where the KEYS tab only show items that have had keys already set.
again, thank you and bravo for this amazing addition to the the dopus arsenal!
