Coming in 0.0.7 Beta :
-Pressing Enter in the ReaBin list pastes to REAPER.
-ReaBin list has a context (right-click) menu, now with 2 operations :
*Copy Bin take names to REAPER takes. (I.e. the takes that will be pasted to Reaper timeline. Handy if you end up with "Dog Bark (001)"-style names in the ReaBIN and want to have those same names appear in the pasted REAPER takes.)
*Replace take selected in REAPER with selected take of ReaBIN. This may exhibit "exploding" behaviour as it sends several REAPER command messages at one go. I'd be interested if it works as advertised...Won't work with multiple takes yet.
Also if all goes well : "Replace take selected in ReaBIN with take selected in REAPER"
