I have read the FAQ.

If I click the save button, it does save the changes, but closes the settings window. This is annoying when you have several changes to make. Adding an APPLY button would resolve the issue. If changing to another settings screens and there are unsaved changes, a warning message could be displayed.

I'm honestly not seeing the problem here. You say when you click Save the changes do get applied. If you have to make multiple changes, just make multiple changes and save them all together at the end? Or am I missing something here?

Make a change on one screen, but don't click save. Move to another screen, then back to the original one you made changes to. Changes are gone.

Steps:

1. Settings->GCODE scripts
2. Type something one of the boxes like "M70 P1" in the After print job completes box
3. Click "temperatures"
4. Click "GCODE scripts"

Expected:
The thing you typed in step 2 to be in the box where you typed it.

Result:
It's gone

Why is this the expected result?
So the user can change some gcode scripts, some temperatures, revisit some gcode scripts, change some plugin settings and then hit Save and have them all go at once.

The steps I gave repro for me on devel: fcdb556

Please tell me what I'm doing wrong: Video

Just checked this out on the latest devel branch and it seems to be keeping the changes when switching screens.

[markwal]

Ha ha. It's fixed by my pull request 3e5298f.

git checkout e5de000
reload page
repros

git checkout devel
reload page
no repro

I'm guessing because that change stopped the "show" propagation and somewhere in there something refreshed the settings data from the server and now it doesn't.

[markwal]

Yep. That's it. Just verified in the debugger. In settings.js, self.onSettingsShown used to get called on every pane change and refresh the data from the server. After 3e5298f it doesn't.

[foosel]

Perfect, another mystery solves then. I was honestly starting to doubt my sanity here :)

Ok, also updated the Changelog, closing this
