dear goetz, thank you for your reply
of course i tried all available alternatives, obviously failed
and, yes, of course i have external usb mouse, but i try not to use it, nevertheless, i just plugged it in
despite that, i kindly suggest to add laptop input alternative, ie
holding both left & right mouse button ( since there is no middle button ) would be my preferred suggestion, other suggestions would be
ctrl+left mouse button ( quite uncomfortable ) or
space+left mouse button ( still uncomfortable ) or
user-defined hotkey combination
also, as a long-time computer user ( i am 48 years old ), i had to buy a few new mouses because middle mouse button failure ( sketchup is to blame lol )
have fun
best regards
aum
ps : i checked numerous model railroad apps, 3d train studio won the 1st place, hands down - beautiful simple graphics, modern ui ( except missing dark mode lol , this goes for webpage too ), lua is my favorite language, community-content, blender to the rescue etc.
somebody is doing a great work for model railroad digital enthusiasts. extremely well thought app. bow
love it, keep the good work rolling ...
