that fiddling is building some plugins yourself, or grab other stuff that has LV2 versions, for example:
Installing the macOS version of these plugins, and copying their LV2 bundle inside the LV2 dir inside mod-app.app allows it to see those plugins and load them as-is.
As a bonus, if those plugins support the LV2 “UI show interface” extension, a button appears on the MOD web gui to allow to open the desktop GUI of such plugins.
for example, master_me on the windows 64bit build, notice the new 4-square windows-like logo on the master_me tuna can
