I care about every single user, and the fact that every question you write here is answered immediately is prove for that.

Of course, I cannot create special builds for every single user who demands it. Everytime I release an update I would have to create dozens or thousands of builds and test and maintain these builds. You don't really ask for that, do you?

You write here completely anonymous, so I have no way of knowing whether you are one of my corporate customers who may, of course, ask for special services. I understand now that this sentence could be interpreted as cynicism, but it wasn't meant this way. Sorry.

Finally, yes I tested the Ctrl+Cmd+O (the first time you mentioned the problem), but it just does not work. If you set a custom keyboard shortcut for the Finder to Ctrl+Cmd+O, it will no longer respond to Cmd+O. So that is not a possible solution.

In the end it boils down to this: Should BetterZip support Cmd+Down Arrow or Cmd+O? It's an exclusive or. And having in mind many other users, I decided to go with Cmd+Down Arrow. For now. I am not ruling out a user customizable shortcut system, but features like AppleScript and contextual menus have a much higher priority.
