Add search filters support on landscape orientation

Hello,
I use a android mini PC with a 1080p hdmi display and have the pro version of XiiaLive running under android 4.4.2.

Since the app is running in portrait / landscape mode all the time (please don't ask me to hold my screen 90° to another direction while I am searching) I have no access to some features like the search filters when searching for a keyword in shoutcast. I think there should be enough space to put in the filter line again, even in portrait mode, especially in high resolution environments. Or is there a quick fix you can suggest?

Thanks in advance for your help!
