didn't review everything yet. It basically works, but looking at the comment in the migration step, I think this part needs a rework.

general comments while testing:

• sidebar view is not working well the selector expands over the sidebar and is only half visible (TagSelector is quite similar we can probably take some of that)
  and when clicking on the selector the selector overflows the initial div:

• clicking on the radio button in the list opens the dependent card and does not mark it as done
• debatable: I think we should have the selector not show all selected cards and show it again below. Makes it feel cluttered to me.

It is strange. I cannot reproduce this issue. It works well on my side.

For now, this is just an icon to indicate the status of the depend card. Hmm... it is reasonable to add a quick done button for the depend card

It sound reasonable. I think we need design advice.
