Suggest Feature: Collapsible Lists

[ming997hk]

Propose adding a collapsible list feature to Planka, enabling users to collapse or expand lists on a board to minimize clutter and enhance focus. This would benefit large projects by saving screen space and allowing users to hide less relevant lists. Implementation could involve a toggle button (e.g., a chevron) on list headers, with collapsed lists displaying only the header. Optionally, the collapse state could be saved. This would streamline the UI, similar to tools like Trello. Thoughts or feedback on this idea?
