Show suggestions when adding tags
Typically when I encourage our employees to use tags, I find it very important that the same tags be used for the same types of content. Unfortunately, often different people will misremember the tags and/or misspell the tags. The end result is that when someone clicks on a tag, they do not find all of the data they are looking for.
For example ClientInfo and ClientData might be two different tags intended to be for the same type of data. If, when typing tags, it showed previously used tags, it would greatly help keep the system synchronized.
As follow ups, it would be idea to be able to see all tags in the system and edit/rename them from some sort of admin screen. Possibly even add tags, so that the admin could provide the desired tags up front, before users begin adding content.
