UI convenience suggestions:

Can the search screen come up with the cursor already in the search box?
Can the <enter> key function the same as pressing the "Search" button?

Random observation:
If you are surfing for stations, then select a streaming station which brings up KMplayer, then while that station is playing in KMplayer switch back over to RTG & select another station, RTG brings up another instance of KMPlayer so that both stations are playing at the same time.

Maybe in settings there should be an option to open new stations in the player already running?
