I asked in
https://invent.kde.org/kdevelop/kdevelop/-/merge_requests/559#note_940928 an
question that inspired me to put up this feature request. I mostly just want to
remember this idea, so that I or somebody else could perhaps try implement this
some day.
Looking at my `sessionrc` I see that an `[Working File Sets][code_9925939][View
0 Config]` doesn't store any information about of its order, at least
explicitly.
The `[Working File Sets][code_9925939]` list of view's seems to be sorted in
lexical order:
```
View
0=file:///mnt/source/kde/src/kdevelop/kdevplatform/debugger/breakpoint/breakpointmodel.h
View
1=file:///mnt/source/kde/src/kdevelop/kdevplatform/debugger/breakpoint/breakpointmodel.cpp
View
10=file:///mnt/source/kde/src/kdevelop/kdevplatform/sublime/tooldocument.cpp
View
11=file:///mnt/source/kde/src/kdevelop/kdevplatform/sublime/idealbuttonbarwidget.cpp
```
So I'm assuming once a document tab/view is closed, it's removed from these
structures, and therefore, I think KDevelop is unable to remember the tab/view
ordering of any closed documents.
Reordering of the document tabs while they remain open works fine, and this
order is persistent. However, KDevelop seems to forget this ordering as soon as
the document tab/view is closed. The default re-opened position of a tab/view
thus feels wrong most of the time, and the available configuration settings
don't help much.
So my proposed idea would be to save an ordering hints per URL, to enable
`openDocument()` to restore an opened document tab/view at its former position,
or at least nearish to it. This would take preference over the current
configuration settings "Open new tab after current" and "Arrange related
document side by side" when the ordering hint is available.
* Option in the configuration UI: "Remember closed tab order" opt-in.
* Closing a document would save/update its tab/view order as an hint for the
next time this URL is opened.
* If the URL's file on disk ceases to exist, the kdevelop could then clean up
any tab/view order hints of such URLs. (to not bloat the config indefinitely)
Or alternatively, remember only last N closed tab/view positions.
