Almost the best implementation of Keepass. But:
1. TouchID is globally applied to all databases. In my case, Id prefer to have choice - which database password can be stored in touchID controller, and which Id rather typed manually.
2. Custom fields values always visible. Better to hide values with "Protect in-memory" turned on option.
3. Dropbox syncing works like a charm. But - desktop application checks file ".DatabaseName.kdbx.lock" and if it exists - opens the database in readonly mode, otherwise it creates this lock-file. So - this way its possible to avoid syncing conflicts. If you add this functionality - it would be a killing feature.
