Ok so here is my only real and, so far, unrelenting CON for the new layer manager. It's real time. There is no "make change, THEN apply"... if I am going down a list of layers to freeze, and choose to click as I go, rather than make my selection and THEN freeze... it's doing a REGEN on the drawing every time I click and turning off that layer.
This can get quite laggy and interfere with fluid user interfacing. I tend to not hold CTRL and select layers THEN make the mod, because I sometimes mess up and have to restart the selection set process and it can be annoying sometimes... anyways... that's it
It's real-time and that can be a hinderence.
