Interface layout save after reinitialization

[wbinek]

Describe the bug
The save of interface layout is disabled after clicking on "Window->Reinitialize interface" in the session. I am not sure this is a good behaviour. If I mess my layout I use the reinitialization option and then the fixed layout is lost on next app start.

To Reproduce
Steps to reproduce the behaviour:

1. Set wrong/messed layout, close app (the messed layout gets saved)
2. Start I-SIMPA againt, use Window->Reinitialize to restore starting layout
3. Close app (the fixed layout is not saved)
4. Start app again (messed layout is restored)

Expected behaviour
I believe that it would be better to save app layout regardless of reinitialization.

Desktop (please complete the following information)

• OS: Windows 10
• Version: Custom Build
• Build date: Custom Build, 20.04.2021

Additional context
The behaviour can be changed by commenting/removing the 645 line in i_simpa_main.cpp file:
saveManagerConfig=false
I can create the pull request for this issue but I wanted to discuss the issue first.
