This is an old one:
(In case this haunts only me and nobody encountered and needed that previously so it didn't make to a request post here)
This behaviour bugs me everytime:
When you Alt+drag the clip to make a copy to the right - next to its tails [with the magnet button for sticking to clips is enabled of course] it won't stick. It would stick however if you alt + drag it to the left to stick to its heads.
And what I'd do as a workaround for many years is alt dragging the first one a track up then reselecting the bottom one and alt dragging it to the right so it'd sticked to the tails of the one above the original.
The summery: it drags and sticks around anything but the tails of the the clip it has been dragged from
Could you please fix that?
