I have already been able to test this extension and I am really happy, if it fits your needs it is a must have, it works really well, very polished and looks really promising to become a top support software even for users who have not heard of Flarum I think they will end up taking a look at it.
After testing the extension for a while, I have come up with some interesting ideas, I want to share them with you in case you like them or maybe other ideas come from them.
Part of it came to my mind when I read (in the survey) about the department system that you might add, but actually this feature could be added without having the department system. Basically a new selector would be added before the language selection, where you could select the categories (previously configured in the admin panel) of the ticket, for example; General support, General questions, Technical help, Questions about my account... etc.
This way you can see at a glance what the ticket is about and it could possibly work very well with departments as you could send X category directly to X department.
This feature might remind you of UserVoice if you have seen this service somewhere on the internet, the system would actually be very similar to the tickets currently in place, technically it would be like a "public tickets" but dedicated to suggestions/ideas, this way users can post suggestions publicly and other users can vote to note that they like the suggestion.
There would also be a status for the suggestion as with normal tickets so that when what is requested in the suggestion is fulfilled, it would be marked as completed.
This in particular would be quite useful to be able to have Knowledge base articles translated.
This is all I have come up with so far 😅
Many thanks to the @v17development team for this extension, keep up the great work!
