I am basically done with the work (beta status oc). I will credit you (and the BiggerUI creator, once he gives a go to it) as owner(s) of the original mods + will be linking to the originals.

As for installation order, atm it would be required to have StellarisUI installed first in list (integrates fonts way beyond what BiggerUI changes oc), but no longer BiggerUI itself since I have used his COMPLETE source as base for modding Stellaris ... ^^

It is possible to reduce the actual release to only fixed files and no GFX, which would require BiggerUI still be installed beforehand, but honestly, I would like to do it the other way around though; it would ensure compatibility with Stellaris - even if it updates - while he can update BiggerUI autonomously in the background without changing any code base for me - and I can go synchronize it afterwards.

PS There are things fixed in my version that are not only broken in the ORIGINAL Pdx release (wtf^^), but also in your Stellaris oc; alignments and some development sort GFX (provinceview) basically. You might want to compare my version with yours in order to fix that stuff in your releases also.
