Apologies for the late reply, I was too busy actually using this Add-on and rating my music
Yep all good ideas, I would add to it a couple of things.
- Playcount syncing (I think this can easily be done by just adding a playcount field on the searchtracks and searchalbum API
- I think its important when looking at syncing "up" to TADB to look at the api usage and try to keep it as minimal as possible.
- Yes TADB has an "add to collection" feature. This is not available from the API yet, but I don't see why it couldn't be!
- I believe there is already a "more information" button provided by the extended info Add-on by Phil65. To be honest I don't know too much about it, but I think he already has those bases covered.
- We need to add a proper API key at some point, I will PM you with one soon.
