- [
] "1. wine 32 bit from repository breaks the system-wine 32 bit Appimage works keyboard only partially." ← need steps to reproduce. I have successfully installed PlayOnLinux, no issues. - [

- [] "6. indicators and ayatana ones are conflicting but well the work both. Same for the appmenu globalmenu applets. Two sets of conflicting packages that do exactly the same thing." ← details needed. If you instal Unity along with MATE, then it is actually not supported. Unity is dead, you should understand this.
