Hi David, # With regard to question 1, issue:
window position,0,0 # followed by window size,7860,2160 # With regard to question 2, launch with the -j option to get the gui drawn twice, or issue: stereo geowall # and if necessary: stereo swap # With regard to question 3, we don't have a solution yet, but we are going to have to solve this someday soon!
