Feature Request: Workflow folder and tag

### Feature Idea

After a while of using comfyui, there would be many workflows, and the list becomes very long.
So suggest to add folder and tag to the workflow org and mgmt.
Also, it would be better, if there is one recent used (maybe 5 - 10 or configurable amount) workflows on the top of the worklist, above the workflow bookmarks.
Thanks.

### Existing Solutions

The search box works well, but not very convenient.

### Other

Many resources like models support the folder and sub folders.
