How about an option to set a wallpaper in renoise of your choice? I mostly only use 4 or 5 tracks in a song which gives me a lot of empty space on my screen 
You know that you can design your own skin for Renoise don’t you?
Try browsing the skin folder inside the renoise program folder for viewing the structure.
yes i know i can change the colours/themes/skins but why not an actual wallpaper of your choice?good idea or what? 
maybe the ability to make it pseudo transparent? (meaning it would show your desktop wallpaper)
would use an unnecessary amount of valuable resources. but would look nioce.
a few terminals in linux, and the main terminal in osx has this ability. wish i knew of one that did in windows. but all that is offered to windows users is normal transparency which is totally useless to use.
