[Request] Add a way to update progress percentage from the Kanban view

[a-elder]

Progress percentage looks great as the completion bar on the bottom of each card in the kanban view, but there is no way to update progress in the same view.
I suggest:

• Automatically update progress when cards are moved between columns (into in progress, 25%; into review 75%; into done, 100%)
• Create a button in the card upper properties menu to change progress like you would with status, date, priority, assignees, etc.
• Both?
  Or even better, a drag-able slider in that section (maybe that's just me, and would be a lot harder to implement).

Hi @a-elder thanks for the suggestions.
We have deprecated the slider option that was in one of the very early versions because it's way harder to scale it properly in smaller windows and tight columns so for now it's going to be a simple numeric input.
As for the automatic updates - that might come in a future version since we have to see if that's something other users would like to see as well. Currently we had different scenarios for the progress tracking proposed but they all different with no clear favorite.
