I actually found this poll because I did a search for "Kagu volume" to find out if there was any way to control the volume. Now that I know it can be done with the buttons, I actually kind of like it that way. My preference would be to have a volume icon somewhere on the now playing screen that would pull up a volume slider; if the user pressed the "zoom" buttons at the top, it could also pull up the same volume slider but control it in 10% steps. Someone before me mentioned a vertical slider for the volume which I think would be neat since it's a little different from other media players and it's closer to what I'm used to seeing on mixing boards.

As for the seek control, well, I almost never ever use a seek control since I either listen to an entire song or skip it and I haven't listened to many audiobooks. However, I find that I frequently have to use the seek control in Kagu because I keep accidentally starting a new song (or restarting my current song) when I'm trying to scroll through the song list. Then ,when I restart the song I was trying to listen to, I have to try to figure out where I was and while trying to scroll through the list of times, I hit the wrong one. For that reason, I'd like to see the seek control be a slider and/or it would be helpful to me to have different regions of the screen for scrolling the menus and selecting the menu items.

That's my experience with Kagu so far. I've only been using it for 4 days or so, but I'm liking it a lot. I appreciate the fact that you seem very active in the IT community and you actively seek your users opinions about the software you're writing. Keep up the good work!
