Better support for tag management.

Tags are a great way to organize your space and query. However, it would be nice to have some additional support for managing them better.

• Renaming
  While it is possible to try and do a find & replace for occurrences of #tag across a space, it would be convenient to have a way to rename them across all of your pages. Linking to a related feature request Support for nested tags. #1148, which might be need to taken into account when implementing this.
• Navigation
  Some way to quickly find and navigate across your tags, maybe a Tag Picker akin to Page Picker. I understand that there is a 📌 {{tag}} but the only way to actually reach this is to click on a tag.
  This would be move convenient than trying to do a search across your space, or writing a query every time you need to find a tag.

tag-wrangler for Obsidian is a plugin that provides some tag-management functionality so it might be a bit useful to take a look once on the approach here.

I am not sure here, but maybe this could be done within a Tags plug which ships with SilverBullet similar to Editor.
