I find that when I am trying to recall what I should try to do after the end of a line I am trying to master, yes words are nice, but a visual is sometimes better. That is to say: being able to draw arrows to show ideas. Ex: Be7->b4->a5->b6 rerouting a bishop on a different diagonal.

That was what I had deemed the correct regrouping of a bishop in a Dutch Defense line after some calm situation occurred. I started to write it in the comments section, but being a good 'visual learner', thought how convenient it would be to simply draw arrows, rather like you can in ChessBase.
