Features request for Depot. Thanks.

It's really a very good and useful software.  Thanks.

1. I want to use it to set up a documents depot.  So what I concern is that if I can locate the meta data to the depot itself?  And it could define a root location.
For example, I use E:\Documents as a depot.  Then, I can use your TaggedFrog open a depot which has the root location E:\Documents.  All the meta/database was written to a fold inside E:\Documents, e.g. :\Documents\.meta.  So I could use a mobile disk as a depot and I won't worry about a re-installation of the OS.
Also, users could setup multiple Depots.  They could open a depot before they wanted to manager it.

2. A light resource/file manager.
Users could add a new file to the depot through TaggedFrog.  I mean through TaggedFrog UI, copy or move a file into the location of the depot.

3. Apply a optional feature to store the hash codes of every file beside tags.
When copying a new file to the depot (through TaggedFrog), a background task could run to generate hash codes and record it.  Also after the process, search to see if the file was already existed in the depot and report like the red ball.

Just some suggestions, it really a very good tool!
Thanks again.
