Please add the ability to select all occurrences of a given object, as follows:
When editing in piano roll view, I can right click on a specific note on the piano roll, and see a context menu option to select all occurrences of that note in the clip or the entire track.
Also, in the arranger window, I could right click a track and have an option on that context menu to select all clips in that track.
Having to drag over multiple clips or MIDI events to select only them is, well, a drag.
