Some background - I mostly play with my parents or friends that I'm on Skype with. I rarely match against strangers online. I play 1-3 times a week. My username is the same as here, StarShade. As requested, I'll answer each in terms of how useful it would be to me specifically.
Here are some features we have on our wishlist; please let me know if you would appreciate/use them:
1. An offline client, allowing you to play campaigns against bots.
Would not be useful for me.
2. A bot with a setting for different play styles
Might be interesting but not a priority
3. A strong bot.
Might be interesting but not a priority
4. Options for timed games
No interest
5. Options for undo settings
No interest
6. Online mini-tournaments; the option to easily create one for you & your friends.
This could be nice, but probably wouldn't be as nice as some of the other suggestions
7. Option to invite specific players to your table
Yes, please! It's confusing and unintuitive trying to help new friends join compared to the previous version.
8. More translations (to what language?)
No interest
9. Better animations when cards are gained/bought/played/...
See next answer
10. Better visualization of split piles, Archive/Crypt contents, Prince targets, ...
In general, visual animations and intuitive layout is an area that I think could use a lot of improvement and polish. When things happen automatically or in response to other cards, my parents get confused. It might be helpful rather than splitting the prompts/choices in the log, buttons that appear to the side, and the cards themselves if it showed the causing card and the choices (with extra information in tooltips or hidden under a more info button) together in the middle of the view. The website also doesn't seem to work very well with varying resolutions. I don't always have it full screen and my dad has a much narrower monitor than most, which can cause things to be cut off. This is the biggest priority for me.
10. Option to hide the log
Not a priority, but could help clean up the UI
11. Android app (or just improved compatibility?)
No interest
12. iPhone app (or just improved compatibility?)
No interest
13. Downloadable game logs
Nice to have but not a priority
14. Improved moderation (dealing with chat abuse, slowplayers, ...)
No interest
15. Tutorial on how to play Dominion
This could be useful, it's hard to describe stuff without seeing their screen.
16. Tutorial on how to play dominion online.
Similarly to 15, this is hard to describe over Skype without seeing their screen. This could be helped with a more intuitive interface though.
