I cannot imagine actually using or desiring such a thing. You are free to ask for new features – but, as the Read Before Posting and FAQ sections thoroughly explain, feature requests in this Community will do no good, and will not be seen by the developer.

If you do make an official feature request as described in the FAQ, I doubt it will be implemented. And I’d personally prefer that the developer spends time on some of the persistent bugs or feature requests that have been around for years on features that people use every day, rather than on cosmetic things like “gradient backgrounds”. But my preferences don’t decide what actually gets worked on, so who knows what might happen.
