The wayland plugin would require at least debian 12 (or ubuntu 22.04) at runtime.

Some checkboxes, e.g. main_window.warn_if_testnet became buggy with pyqt6:
looks like the stateChanged signal passes an int, not a Qt.CheckState.
(and note that Qt.CheckState is an Enum, not an IntEnum).
So `x == Qt.CheckState.Checked` would always evaluate to False.
```
def on_cb(_x):
print(f"heyheyhey. {_x=!r}, {Qt.CheckState.Checked=!r}, {cb.checkState()=!r}, {cb.isChecked()=!r}")
cb = QCheckBox("")
cb.stateChanged.connect(on_cb)
```
heyheyhey. x=2, Qt.CheckState.Checked=<CheckState.Checked: 2>, cb.checkState()=<CheckState.Checked: 2>, cb.isChecked()=True
heyheyhey. x=0, Qt.CheckState.Checked=<CheckState.Checked: 2>, cb.checkState()=<CheckState.Unchecked: 0>, cb.isChecked()=False
macOS reserves the "About" menu item name, similarly to "Preferences" (see a few lines above).
The "About" keyword seems even more strictly locked down:
not allowed as either a prefix or a suffix.
- With Qt5, a matching menu item is simply auto-recognised as the special "About" item,
- but with Qt6, it seems we explicitly have to do this dance, as directly adding
a menu item with the "About" name results in a segfault...
I noticed that when running from source on macOS, the OS menubar has an "About Python" menu item,
instead of an "About Electrum" menu item. I tried to fix that by this, but actually it is not working :P
Nevertheless, this looks useful at least on Linux and Windows. E.g. when instantiating a new dialog
without an explicit title, the qt application name is used as default.
The application name, without this change AFAICS was already "Electrum" when running any of the binaries.
However when running from source, it was in some cases "python" or "run_electrum" or even "electrum-4"
(depending on OS and how the main script is started).
Now it is consistent -- except on macOS it still is not, as there it really wants to look for a .plist...
In some cases this makes it much easier to successfully scan a QR code.
I was trying to scan a PSBT using a laptop camera from my phone screen for 2 minutes, until I realised the screen brightness was the issue. o.O
- between the Back btn and the Next btn, the latter should have priority for focus
- but if the user needs to enter the wallet password, that textedit should have focus

Some functions have an argument named "seed_type" in which it was annoying to call the seed_type() fn.
(especially for functions inside the same module)
instead, schedule a queued finished signal to unregister the listener after the handler has finished.
See PythonActivity.java in P4A for why this probably causes the most often occurring crash we see on the Play Store:
