Closing conversations in bulk is annoying in the dashboard

[cheeseblubber]

Problem
I want to mass close conversations and the UX is slow and I have to wait for the delay.

Solution
Instead of delaying the closing when pressing cmd + D have pop up notification on the right side that lets you reopen the conversation

Describe alternatives you've considered
Bulk closing where you can click on multiple conversations and close it. (This partial solves the problem because sometimes I want to read the entire thread before closing a conversation)
