I've gotten pretty far in replicating most of the Logic features I use all the time but there are some I haven't found an answer to:
1. There's a Logic feature "duplicate selected regions to selected tracks". I know of the Copy Selected items to Mouse Cursor in Reaper action but I think it's way faster in Logic. I can just select an item, use my arrow keys up/down to select a track and it neatly duplicates the region (items) right at the same position as the original item but onto the selected track instead. With Copy Selected items to Mouse Cursor I still have to move my mouse (trackpad) and point to where I want to paste the selected item. The Logic way is faster.
2. There's a Logic feature called "Pack Regions into Folder" whereby you can select a few items, hit the key command and it will pack the selected items into a "folder" that perfectly snaps to the nearest bar which then loops seamlessly:

I know of the loop item feature in Reaper but I think this Logic way is faster.
These are the only two I can think of right now. Otherwise I'm really enjoying Reaper!
