I yesterday assigned this to @ajdapretnar; for this one, maybe @VesnaT would have to check it, too.

I think considering this PR is dealing with apply, it would be nice if it fixed the mismatching buttons in Color and Concatenate, which are unlike those of other widgets.

[janezd]

This is one of supported generic options. It is more obvious than the usual (checkbox without a label) but we seldom use it because most widgets are not wide enough. I can of course remove it (the label is set by an explicit argument to gui.auto_commit, so I just have to remove the extra argument), but I'm undecided about whether the extra explanatory label indeed bothers me. @markotoplak, @irgolic, what are your opinions?

All widgets in this PR works correctly now, so I will merge it. With this PR debate about the inconsistency of auto-commit button started. I will open the separate issue to continue it.
