I know these have been mentioned before but I feel like mentioning them again :-) I would love to see the two following features implemented into Reaper:
1. Icon or clear indicator on each track that lets you know if it if "FROZEN" or not. Several times I have started messing around with a track and then realized, oh darn, I should have "Un-Frozen" it first!
2. Open the midi editor with the area clicked on appearing center. Many times I want to make an adjustment to a long midi drum item towards the middle or end, and when I click on it to open it I have to scroll and scroll and scroll to find the notes I want to adjust. Give me an option to click on a section then open with that area appearing in the midi editor front and center. This would be such a time saver in the overall workflow.
Thanks for all your great updates. Reaper is still my DAW of choice.
Also, need the option to route virtual instrument sends to other tracks PRE-FADER so you can record the input before the receiving tracks effects. Currently if you want to record the tracks raw, you have to disable all of the effects then record the output of that track.
