1) Don't worry for careless wording :)
2) Drag-and-drop might not be good mechanics for everyone and I am aware of that. I am otherwise always in favour of lowest/simplest interface decisions (and in 90% cases I saw I didn't like drag-and-drop usage), but it seemed the most natural thing to this specific usage to me (basically connecting many to many items). But as I said, I am aware some will hate it.
Well I am from Slovenia and my browser is in my language so "File Open" form is in Slovene language yes. I see that this might look odd on video but at this point I am more trying to get the message across (what it's about / how it works) than to impress / sell it so someone, so I don't care.
3) What do you mean by whole conversation?
4) No. And there is a lot of things on the same level that are not there yet. Something I call "filters" (and is quite needed) is in the making but is not yet done because I haven't yet found good answers to some questions for example.
5) Not at this point.
6) Yes, you could write your own solution of course. You can probably see some differences compared to sending feedback directly to email. Sending it to email has some benefits too compared to this, but in general we can do much more with it. Some of these things can already be seen, some will become more apparent when usrjoy gets also the less core functionalities.
7) There is no HTTPS there right now. This is first public beta release. There will be. For comparison in our other service that is more mature we have HTTPS, API and Data Export and we intend to do the same here. I am strong believer that user's data is hi/she-s own.
Thanks for your questions. I asked for critical feedback and I got it :)
