Label-studio: Overlapping audio regions

[makseq]

I am trying to annotate "multilabel" audio regions (which is basically multi-label for my video segments); my problem is that after selecting region1, if region2 starts after region1 does, theres no way to label that overlap because instead it ends up _moving_ region1. I have added in an example screen recording when I tried to do this on the playground too, so I think this may not be a feature yet...but definitely a useful feature to have

It seems to work if region2 starts before region1 and continues into region1, though.

@stalagmite7
Try to select the region using Results panel

[stalagmite7]

But its not about selecting region2, its about trying to _create_ region2 with a starting point that lies between region1's starting and ending point. To create region2, i have to move region1 out of the way after remembering its position, mark region 2, and move region1 back to its original position

@hlomzik it seems we need to note this. One of possible solutions is to lock underlying regions with special action (e.g. lock icon in Result panel). And after the lock regions are not affect anything.

Oh, yes, this is important problem for audio/image regions, because we don't want to loose ability to move them easily, but it's necessary to create them in any place.
The good solution is to move regions only after selecting them. So any drag would create new region, because creating regions is more important than editing them.
I think that's better?

What about a lock button? Something like Photoshop or image editor layers. If you block a region you should be able to overlap new regions without move the blocked ones

@jonorozcoc In the last releases we added "eye" button to hide regions, it can be used as lock in some meaning.
