I'm really starting to like EasyEDA - many nice features compared to my older version of Eagle. A couple questions: Is it possible to lock the PCB origin?  I finally figured out why it keeps changing....I hit the home key when reaching for delete, and my careful parts placement gets screwed up.  I rarely have reason to move the origin once I start arranging things. Is it possible to change via dimensions en masse?  Once again, I put down a bunch of vias and I want to make them all larger.  Is there a better way than editing them one by one? Thanks, Jonn
