You can probably get a GUI designer to come up with a new and modern more timely vector based and scalable GUI for around 200 USD. While you are at it, also have a dark mode made. That's like the cost of one or two pro version licenses... Screen resolution at 4K will see your current GUI at around the size of a stamp. It is also not very friendly for users with a visual impairment.
There is really no excuse for keeping the look and feel of the current Windows 95 user interface (which was 28 years ago).
I am pretty sure BRU could double its sales just by updating its user interface look and feel to something modern.
I think it really is time for an new UI experience.
