Which menus are bloated or do you mean pref pages for menus ?
File association will be done when I get around to it. It's just not something that I'm offering in the current on-going beta / preview state even though it's already possible to manually associate things via the OS "open with" action or there's a tool by nirsoft that can do it iirc.I know I can use Open With, but I didn't mean to ask about file association, a I know it will take time, rather about the file icons customization, which will probably take even LONGER...
For the menus if you go to Preferences -> Appearance -> either un-check the option for skinned menus to be whatever the OS wants to do for them or un-check the common ui font option & pick a lower font size which can lessen their overall sizing & perceived padding due to things being based around the specified font information vs whatever OS text scaling aspects might also be getting involved with the rendering & is an intentional difference vs whatever winamp might've done as wacup is not winamp.
https://www.nirsoft.net/utils/file_types_manager.html (https://www.nirsoft.net/utils/file_types_manager.html) is the tool I was trying to remember which'll allow you to do what's needed without having to wait for me to potentially never do it.
