When you try to open a file already opened on another system (ex: in a shared folder), you get a warning dialog giving you a few action choices, as seen in attachment #180851 [details]: * Open Read-Only * Notify * Open Copy (if the file was locked by *another* user) * Open (i.e. override the safety) * Cancel Notify seems to be essentially "Open Read-Only" but with the extra feature that it will notify you if/when the document's lockfile is released and the document can become read+write (barring situations like bug #165572 where it doesn't actually notify you). As such, I see no downside and no reason why you would want to use only "Open Read-Only" instead of using "Notify". Therefore, my suggestion here is: * Consider making "Notify" an integral default part of "Open Read-Only" feature (and putting an explanatory mention of that in the dialog's message text instead), and eliminating the separate action for it. * Ideally, for the GTK version, you would also set the blue "suggested-action" CSS class on the resulting "Open Read-Only [with notification]" button to indicate it is the most recommendable action; see https://developer.gnome.org/hig/patterns/controls/buttons.html#suggested-destructive-actions for reference, but such styling is already used elsewhere in LibreOffice (implemented in bug #150007, bug #150008), so you also have existing code for this as reference, too. ---- Version: 25.2.1.2 (X86_64) / LibreOffice Community Build ID: d3abf4aee5fd705e4a92bba33a32f40bc4e56f49 CPU threads: 8; OS: Linux 6.12; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US Flatpak
