1. There will be multiple face variants for each faction.
2. Healing animations are planned. How they are going to be implemented- who knows, but you can watch a sneak peak of them in the 2016 dev report on youtube.
3. There was a suggestion like that on one of the streams, Nikita( CEO of BSG) said that it's a cool idea and they'll think about it.
4. Can't really say anything about that since i don't understand the issue.
5. Weapon jam mechanic were actually in the game in the first early alpha builds, but were removed for tweaking and reworking and will come back at a later stage.
6. Picklocking is a feature that is also planned, you can, once again, watch a sneak peak of it in the 206 dev report.
7. That's a cool idea, but probably very hard to implement.
