All the effect checkboxes have now been set to ON by default, and are sticky (meaning that if you disable preview, on next launch of Illustrator preview will remain disabled). This functionality now is available in our latest release build – 24.1.1 for Win and 24.1 for Mac which is available worldwide now.
We are working on making all remaining preview check-boxes sticky. Will update this thread when done!

I'm using the Transform Effect pallet multiple times to finely adjust multiple object appearances.
Each time I open the panel I must switch on the Preview again, to see what I'm doing, which is frustrating after the 100th time.
With overall performance in mind, is there a way to toggle this to on by default, maybe in the prefs or within the panel?
We are pleased to inform you that your request is available in the latest release of Illustrator version 22.0.
