I did this once long ago and this was so convoluted I had to change some/paths in some /,conffiles and I never wanted to do it again.
I've gotten a lot of mileage between the Korla and Humanity icon themes and basically been using them for years and years now. I have always loved the panel icons but always DISLIKED the triangle menu icon. And disliked the 4-Dot square default icon:
I wanted to dust this off again and use if for the menu button. A forum user made these and distributed them here a ways back, so I grabbed one--it's the Budgie ship:
Instead of pulling my hair out I had the stupid luck to find this in budgie settings. budgie has made this outrageously easy.:
see where cursor is? ^^ click there to picture's path (mine was in downloads).
Voila:
Like to bump this up a couple sizes...may try that in nemo-fileroller or GIMP later.
I don't know when that creeped into budgie settings since I check often---but glad I found it.
