I'm noticing two bugs in DSub. One occurs occasionally when I launch the app from the widget by pressing the album art. An error message will pop up stating that the app has stopped. Usually when I relaunch the app, it starts working.
The other bug I noticed has to do with the theming. I have the holo theme enabled. Whenever I first launch the app, the DSub title-bar with a blank screen shows up while the app is loading. This load screen is still showing the light theme despite the rest of the app being in holo theme. Minor bug, but figured I'd let you know about it.
