Liked the look of the project and appreciate you have a Linux version, so I purchased it. Now I feel I am worthy to give just a little instantaneous feedback, as I have not really used it in earnest, but I like to help where I can. A spelling mistake appears in the Sound Libraries section. Specifically `Library Titre`
I know it is minor but if I don't point it out who would?
Thanks for your sterling work. Hope this comment is taken in the spirit it is meant to be. 
Btw I made an SVG of your logo, in case you did not have one already. It is useful on Linux, as scalable icons can be used across many desktops regardless of their size or resolution and still look perfect.
