I apologize for taking so long to respond. The response notification went to my junk mail folder.
1. In the docked Plug-In Manager window (it took some trial and error to get it to dock to the main tab panel), I click on Plug-Ins>Video>FX and it lists all my plug-ins and filters.
Then I take the filters I want and drag/drop those into the new “000 Common” folder. It does remove those filters from the FX folder, but I have no problem with that. I have not had a reason to move any back. If I’m missing a reason as to why I should not, please let me know!
2. You can add those filters to any event, but it only adds with the default setting. When the Video Event FX window popups up, I can then use my own presets or tweak it from there. And I’ve added as many filters as I’ve needed with no problems. None have been taken away or overwritten in the plug-in chain.
It works good enough for my needs at this point, but I still hope Sony comes up with a better solution.
