I like to use GeoGebra mainly to sketch out diagrams and LP problems, then export to PGF/Tikz and tweak it there for use in homework and papers. I’ve been using 5 and this feature works great (although I wish there were an option to change the default arrow, but this is minor). I just tried this in 6 for the first time. First off instead of selecting “export” and then changing the x and y limits to suit what you want displayed, you just download a txt file with the code and no option to change the limits. This is a little annoying but I usually tweak that in TexStudio later anyway. But the main problem is that the code is in one solid block with none of the formatting that was produced in GeoGebra 5, making it tough to see where I need to make edits. I’ll go back to using 5 until this is fixed.
