Feature Request - Reduce the number of themes to 2 - Light and Dark.

[jourmager]

Currently, the program settings have 3 style options, each of which has 6 style sheet options, a total of 18 styles.
As was seen earlier, some of the themes have bugs, the graphic design of other themes is outdated for many years.

It is proposed to reduce the number of themes from 18 to 2 - Light and Dark, which will be designed in the style of modern Windows10/11. Reducing the number of themes will reduce the likelihood of errors in the interface and reduce the time for software testing (9 times :-)).
