"Important chats" simple idea

I usually create separate chats for any curiosities that I explore with ChatGPT, and I end up with a lot of unnecessary conversations. The “clear conversations” button wipes out all the chats, so I sometimes have to manually delete a lot of them just to avoid losing the important and/or long ones.

The idea is to add the feature of marking some chats as important. Those won’t be deleted even upon clicking the “clear conversations” button.
