Feature Request: Support Themes

Using "Dark Theme" whenever possible, even it is some extra effort for some applications (e.g. 7z doesn't support natively but there is a fork/option to add Dark Theme support). Even for MS Excel, Web sites (via DARK READER browser extension when web pages are not supporting it, e.g. Amazon).

Would be nice to get support of "theming" for Dependencies as well.

Options:

• System (using them used by operating system)
• Light
• Dark

Related to #222 but not the same.
