Remove old kernel, QT4+KDE packages from Freespire 4.5 Mate

I've noticed, that Freespire 4.5 Mate contains lots of unneeded packages, QT4 and other not used libraries and KDE-related packages for example:
- old linux-image-4.15.0-32-generic and linux-modules-4.15.0-32-generic linux-modules-extra-4.15.0-32 linux-headers-4.15.0-32 linux-headers-4.15.0-32-generic
- app-install-data
- libc6-dbg
- ure and uno-libs3
- libjs-mathjax
- pluma-common
- kdegames-card-data-kf5 (it's needed for kpat solitaire games, but this game can be replaced with GTK analog aisleriot or ace-of-penguins)
- lots of old QT4 libraries (needed only for old synergy 1.8.8 package, new synergy packages uses QT5 libraries, see launchpad.net/bugs/1757885 )
- lots of KDE-related packages (needed only for kolourpaint, but this can be replaced with mtpaint or mypaint)

All not needed packages takes about 1GB on disk, so, if you remove these from Freespire 4.5 image, it can fit in 2GB USB drive!

I can attach /var/log/apt/history.log file and you see all unneeded libraries and other packages in Freespire 4.5 Mate

Btw, where is Freespire issue tracker, maybe you use github, gitlab or some other system for bug tracking?
