1. An offline client, allowing you to play campaigns against bots
If there was a campain I would probably go through it once (and try to get all stars, if there was a star system). But its nothing I really need.
2. A bot with a setting for different play styles
I never play bots.
2. A strong bot.
I never play bots.
4. Options for timed games
Yes! I would play all my games on timed mode.
5. Options for undo settings
Yes, automatic undos if no information was revealed would be nice.
6. Online mini-tournaments; the option to easily create one for you & your friends.
Would not use it with friends, but would participate in bigger tournaments.
7. Option to invite specific players to your table
Sometimes I would use it. I guess I would rather have a "search game with friend" option, and then wait until one of my friends searches for a game. But then again, I am not sure how often I would use that either.
8. More translations (to what language?)
Not needed for me.
9. Better animations when cards are gained/bought/played/...
I would like to have for instance library better, as its not always easy to see which card you are currently keeping/discarding. But overall, I like the current way. Its fast

10. Better visualization of split piles, Archive/Crypt contents, Prince targets, ...
There should be a way to see the bottom of split piles, though it does not matter for me anymore, now that I know them

10. Option to hide the log
Only in a last step, once I really have all information displayed easily seeable during the game.
11. Android app (or just improved compatibility?)
Would like it, but I have a rather large phone, and the current version, while being playable, is way away from being playable comfortably. So I guess it would need a major overhaul, and I am now sure its worth the time.
12. iPhone app (or just improved compatibility?)
I do not have an iPhone.
13. Downloadable game logs
Rarely needed for me
14. Improved moderation (dealing with chat abuse, slowplayers, ...)
I gues its too much effort to have constant moderation. But an easier way for reportig people would still be nice.
15. Tutorial on how to play Dominion
Not for me
16. Tutorial on how to play dominion online.
Not for me
Individual feedback:
I REALLY would like to see my rating improvement / loss after each game. I think you are using too little gameification in the client. Instead of having a 56.7 rating, it would be very nice to be Lvl 56, and see that I only need a few more wins in a row to reach lvl 57. Maybe having a progressbar that shows me how far away I am from winning / loosing a level.
I sometimes would like an option to only play against people who bought cards as well. While I am usually all for sharing, there is two problems I have with it here: 1) I am not a huge fan of "please wait, need to read cards first" comments, 2) more importantly: People who dont own cards apparently need to wait for a while, right now. That makes many of them leave the PC for a while, or tab into another window. Thus, when the game starts, I often have to wait for them to show up. Not forever, but just enough to annoy me

If there is an easy way to fix this, quickbuy for sauna games should be fixed: If I have a silver, a gold, and 6 copper on my hand, and buy a province with quickbuy, the game might select the silver and the copper for the buying. Then, if I trash one of the copper with the silver, my gold is never played and I am left with 7 coins, cant play more treasures and cant buy the province. Run into this a few times. But still, its a minor issue (as all the issues I have), that would be solved if I could undo without asking permission.
