Thank you for the suggestions! We'll keep it in mind as we continue improving PureRef. Some notes/questions:
1. PureRef is not a browser based application so we don't get a lot for free in this regard, and as we've always tried to focus on specifically reference images we'll probably only consider adding support for content related to this (mainly video support is a heavily requested feature). But this and collaborative editing are the 2 big features that we're considering.
4. We appreciate the feedback and are keeping this in mind for future changes. Changing shortcuts is not popular but we'll see what we can do. When you say "more comprehensive shortcut editing feature" what do you feel is missing from the current one specifically?
5. A first version of translations are available for testing in the recently released beta version of
PureRef 2.1.0. Is there any specific language you're interested in?
For the other points we've noted your request.
