OK, I love REAPER, no question about that, and I'm slowly getting used to its way of doing things. However... I'm finding a lot of speed bumps along the road and I figured I should list them here. Please note that some or all of this might be covered in other topics, and if so, sorry. It might also be that some of these "issues" can be easily remedied in the preferences. So bear with me and feel free to point out if I've simply missed something.
The meddlesome edit cursor. I position the edit cursor at the beginning of a section. Then I double click a part in this section to open the midi editor. The edit cursor jumps to where I clicked, and I have to place it at the beginning again. One would think that setting Seek playback to Top ruler only would help, but no. AFAICT that setting does absolutely nothing.
Not possible to resume playback. Sometimes I want to resume playback at the exact point where I stopped. REAPER will only let me listen to the same thing from the beginning again.
Deleting notes in the piano roll. I'm used to Cubase and it's eraser tool. I.e., I would right click, move the pointer slightly to select the eraser, then just erase notes to my heart's content. In REAPER I have to select a note, the press Del (or use the right click menu), select the next note, press Del and so on. Tedious.
Tiny scroll bar grippers. At high magnification the grippers on the main window scroll bars are a pain to hit, most often I end up dragging the left or right handles instead.
Crude panning. The pan controls could use a higher "resolution", or whatever the correct term might be. Right now you can only pan in increments of 5%, which IMO does not give you fine enough control.
Sorting tracks in the performance monitor. It would be nice if you could click on for example "CPU use" in the performance monitor list and have the tracks sorted, ascending or descending, after their CPU load.
No auto-arm. I want to be able to move between tracks with my keyboard and start playing immediately. I do not want to select the track, then arm it,
then start playing. Major disruption of my workflow, as I often record one part, stop, switch tracks and record the next part without ever touching the mouse.
That's all I can think of now, but I might add more things eventually
