I'm still using Arduino-IDE 1.8.13 as a portable version.
I have some additional boards like ESPs, Seeeduino XIAO, Teensy installed.
I made adjustements like different scheme (a customised dark scheme)
If I want to upgrade to version 1.8.16 will simply copying subfolders to the path of the version 1.8.16 work?
If Yes: Which folders do I have to copy?
best regards Stefan
