3. Go to "Display Settings" and toggle the setting for "Show What's New on Startup" to be unchecked.
4. Save the settings.
5. Edit your openhamclock_lastSeenVersion setting in your local storage to set it to 26.1.3.
6. Reload your browser session. The "What's New Page" should not display.
7. Reset your "Show What's New on Startup" to be true if that's what you want.
8. Click the version number on the top left of the screen and the latest "What's New" should still display.
9. Open the Side Panel. You should see an entry for "Rig Bridge".
10. Click it to verify that the correct Settings screen is displayed.

#860

[accius]

Nice and clean PR — good scope. A few things to fix before merge:

Direct config mutation in onChange — The checkbox handler mutates config directly AND sets React state:

config.showWhatsNew = e.target.checked;
setShowWhatsNew(e.target.checked);

The rest of the settings panel sets local state and persists on Save. This means the setting takes effect immediately even without saving, and the behavior on reload without saving is ambiguous. Should follow the same pattern as other settings.

showWhatsNew not in the save handler — I don't see it added to the config object built in the save function. It may work via the direct mutation, but if the user reloads without saving, the setting could revert. Add it alongside the other config fields in the save handler.

"Rig Bridge" label not i18n'd — The sidebar entry uses a hardcoded 'Rig Bridge' string while all other entries use t('...') translation keys.

Helper text wording — "Setting this true means it will only be displayed when the version is clicked" reads a bit backwards since unchecking the box is what disables it. Suggest: "When unchecked, What's New will only appear when you click the version number."
