I've been trying some of the cool features and found some issues (I'm using 0.25.8.). Can you try to reproduce?
1) Edit > Layer > size: I'm trying different sx and sy (on a simple 10umx10um square):
1, 2 ok
-1,2 NOT ok, does 1,2
1,-2 NOT ok, does -1, -2
2) File > Setup > Rulers And Annotations > Templates
The link "here" does not seem to work.
