- manually fixing matches
- scanning libraries
- deleting items
- create an optimised version
Dash is already in a good direction, it just needs to get more administrative features.
Scanning already exists in dash and I have seen fix match (automatically), but cannot find the latter anymore 
And auto fix match is kinda useless. If it would have matched the right one, then there was no need for fixing the match.
Edit: found fix match, only present in search mode (why?)
Edit2: it is not that useless, but manually inputting the parameters would be great.
Edit3: added optimisation
