Command line (with help of bxtrx) have been greatly improved. There are still bugs here and there, but most commands are there, also, when you do create a shape, is saved in the script list. You can save scripts and execute them later. Most commands are not finished, but they have most code there, most of them depend in 1 line fix to make them work.
At the end you have code completion (activated with Space and hints about param types you should fill in).
Command execution only if succeeds only it will be saved in history list.
Also, there was fixed a bug in command line scanner that commands which require strings, to have removed spaces and to not get parameters at all, but the command to be called still.
