1) I want sane error messages on the client side.
2) I want my feedback on community forums not to be shushed. You screwed up — own it. Community mods aren't janitors to wipe out user feedback.
3) I want the extension to be working no matter what kind of server-side problems you have. Let me know about a sync problem but don't terminate my access.
But if you do think, that for $12 I get to be treated like an dog, too bad, there's enough options for me to take my business elsewhere.
