I'm trying to make some modifications to the default skin (mainly font sizes for plot). I'm making the mods on a Windows PC using Notepad++. My current workflow is:

PC modify the skin
PC zip it

RPi4 select Embury skin
RPi4 uninstall modified skin

PC copy modified skin to RPi4 userdata
RPi4 reboot
RPi4 install modified skin
RPi4 test to see if I've got it right

Unless I reboot the RPi4 I just get told the modified skin can't be installed due to an invalid structure - it installs fine after the reboot!

There must be a better workflow. I'm hoping someone can tell me.
