For better management of board views with many columns, it would be important to keep some less used columns permanently collapsed, and expand them manually when needed.

This would be so helpful for organization!

Upvote.

This would be very very helpful! Means when looking at a templated list you can remove the irrelevant parts for specific areas, and then if they are relevant later you can easily expand them again.

Another vote here, where I have columns for done or closed statuses that I want collapsed, they're clearly much less important than the in progress statuses.

100% needed

Especially now in Board view 3.0, where filtering statuses only hides tasks within them, and not the columns entirely.

And the option of collapsing empty columns is not serving this need, because there might be columns which I want to see even if they're empty, while there are other columns full of tasks, which I anyway want collapsed

Yes please. Would be a big improvement.

Yes, this would be a tremendous improvement for me! Having many status columns is a huge part of my workflow. So much so that I migrated over from Trello mainly for the ability to collapse columns that ClickUp offers. There was a 3rd party Chrome extension available for Trello, however it would break every other update. But the nice thing from my previous set up when it was working was that the collapsed columns were persistent from session to session. Now I need to re-collapse about a dozen columns every time I leave and come back to my board view.
