There is a lot to love in TeXstudio. There's a well-implemented dark mode, everything is customizable, it's easy to install, there's git and svn integration, you can choose how to generate your previews, if any, and the list goes on. Whenever I have to use Windows to build some LaTeX documents (sometimes over 2000 pages long), TeXstudio is my go-to GUI. Add on the fact that it's free, and it's just ridiculous. Consider throwing a few dollars at them to encourage them to keep polishing this impressive software.
