Concerning the first tool: I just added this to the Community Library for you:
Sequence/Populate/Insert Clips into Tracks of Active Sequence At CTI Grouped by Label Color.xml
It inserts all currently selected project items into the active sequence at the current time. Based ono their label color, they are inserted either in V3 (brown item), V2 (yellow items) or V1 (all other items). Here is the block code explained:
As you can see, I first sort the selected project items into lists. I do that, because then all selected brown items can be inserted into the active sequence using a single call of the "add pproject items" block. If we would insert each of them separately, they would all start at the current time and replace/overwrite each other. But now, only the first inserted clip in each track starts at the current time and the next one starts where the previous one ends. Currently, Clips which insert their video in V3 insert their audio in A3, not A1. I think there is no way to avoid this, since the add project items block has no separate inputs for audio and video track (that would be a good feature request, though).
