Kostya, I really didn't mean to sound pushy or turn this into a heated discussion in a bad way.
Once one gets used to a certain app, it's not too easy to start over with another, so I wanted to see if you were even considering any one of these. When I discussed some of these with other developers (privately or via forums) usually feedback was "it's noted, and will be considered" or something like "this is already in the works, and will soon be added" and in other cases "no, we do not intend to add this feature". That's all I meant by my most recent post above, to see if we could get your feedback, maybe something you haven't heard before, and thought it's a good idea, or something you already decided not to include.
Once again, you got a really good app, and if it would mean to get a fund going (aside from app price) or dedicated feature request cost, that also would be nice, however I agree being the sole developer of the app, you got your hands full, and surely this app is not your main source of income and must have other priorities.
Спасибо!
