I have tested it and it works well :-)

I am just thinking about the placement of the new check box because it is actually not the content of Workspace settings. Maybe we could create a new Layout settings static box and place there things related to the Layout?

Suggestion: Layout settings ------------------------

* Save current window layout as default

* Save current single window panes layout as default

* Hide 'Tools' tab

* Hide 'History' tab

* Hide 'Python' tab

We might also disable or completely toss out the three "Hide" checkboxes for Single-Window case. I think it is not of any use when there is the new "Save current single window panes layout as default" checkbox. What do you think @tmszi, @petrasovaa ?

Another (simpler) variant coming to my mind, dealing just with this new checkbox, could be to place the new checkbox in the Appearance tab under the Window layout settings static box and enable it only when Use single-window mode is checked.

But probably for the future, a rearrangement of the checkboxes I mentioned earlier would be needed anyway..

I agree with your suggestion.

Maybe I would leave these three "Hide" checkboxes for single-window mode as well, because they are valid (minimize vs hide).
