Do plugins need to be installed for each client?

Running Joplin 2.7.15 (prod, darwin) on 11.6.5 Big Sur

Do plugins need to be installed for each client? Looks like the answer is, 'yes'

Cheers

Yes. There is an ongoing project idea that might be picked up for GSoC to implement a client settings sync that includes plugins although this is only for desktop, plugins are not supported on mobile yet.
