library is present whether one holds down option key or not
Interesting. I know that the normal behavior is to hide the Library unless the option key is down. There may be a setting that changes this, but I've never noticed it.
it sounds like i do not need to even go to the plist file
I don't think you need to edit that file.
Also is there a way of limiting previews?

is any major difference in 4K
It depends on the size of your display and the scale you use for iStripper.
I have 3 displays
the iMac itself which is set to 2560 X 1440
A 43" Phillips BDM4350 which is 3840 X 2160 and is my main display
A 30" HP LP3065 with is 2560 X 1600
I normally play 1 or 2 cards on my main display at 40% size in small mode. With that setting 4K, 3K and 1080p are acceptable to my eyes. I can notice a difference when a 1080p is playing. Occasionally I'm run a playlist of just 720p cards and play 3 or 4 at a time at 30%. For classic cards (480p ) I use a scale do 20%.
Some people can notice a difference between 4K and 3K cards on a 1960 X 1080 display, but I can't.
On the rare case when I play a card at 80% or larger I can see a difference between 4K and 3K.
A 4K card will require more space on your hard drive and will require more processing power.
