[Feature Request] Add a search bar in collection level.

[Feature Request] Add a search bar in collection level.: It would be nice to have a search bar with a global search for each collection. When there are collections with more diagrams than they can show on one screen, it's hard to search for them. Doing a quick CNTL + F and searching would help, but I'm not sure if we can do this on the browser. But having a dedicated search bar in each collection can help.
