converting files from older versions to the current (V15) takes quite some time... If one click on 'cancel', the 'canceled' file will not be removed in every case -> resulting in corrupted files
- if one interrupts a conversion process, the file should be removed
- the conversion process should have a better interface
-- when actualizing index (takes forever), one should be able to say 'later, please'
--- if this is not possible for whatever reason, the process should stop and the file that was processed should be removed
--- since FM is quite not responsive during that process, one clicks 'cancel' a lot of times - can be a factor as well
---- if there is only one 'cancel' that makes sense, the 'cancel' button should no longer be active after one hits the thing once...
- it would bi nice to have more information during the conversion process, eg how much time it takes (app.)
