I’ve been saying it for a long time. You could add a “tolerance” option in the command line, especially in those commands that use it massively, for example, all over, the shell (but also the booleans …).
For example, the shell operation does not work at a tolerance of 0.01, so it may work at 0.1; it is not possible whenever you have to go to the options panel and change the value, it becomes frustrating.
What do you think, makes sense?
