[Feature request] Remove cache from a bookmark directly on cache page

[+VelkyBobik]

When I want to remove a cache from a bookmark, I have to open the bookmark, find the cache, and delete it on bookmark page. 

Would it be possible to add an option to remove cache from bookmark directly on cache page? Perhaps like on the attached image - in that example cache is already in bookmark *Solved* - I could quickly remove it clicking a red cross or add the cache to another bookmark clicking on green checkmark.

Or am I missing something and this is somehow already possible? Clicking on a bookmark twice just gets me *Saved* twice and cache is still in the bookmark.
