Hello, Andy.
It will be possible (maybe, depends on Breeder) with coming soon beta of SWS, where
will be API function to write ini files.
Lines
Code:
[REAPER-fxadd]
lastview=0
in reaper.ini is relevant to you. So, after update someone (me, for example
) can write script, which will firstly modify "fxadd" context in reaper.ini, and after that load your plugin selector window.
