Add option to toggle style of Kanban tiles / cards

An option to toggle between the new and old kanban tile/card styles would be lovely.

For context, I’ve been using the Kanban cards for years now by themselves to create rather dense boards of notes and TODOs. The recent change in styling sadly not only messed up the entire layout (the size changed so they now overlap and many auto-collapsed), but also the performance in the desktop app seems noticeably worse suddenly (have a beefy desktop and never had much of stuttering issues there prior). Visually too I preferred the old look.
