Clippings 6.2 release candidate 2

What's New:
• Clippings now supports Dark Mode system themes on macOS and Windows. The dark-colored theme is automatically applied to Clippings windows and dialogs (for example, Clippings Manager and the extension preferences page) when Dark Mode is activated on your system.
• You can now choose how you want the date or time to be formatted for the $[DATE] and $[TIME] placeholders; for example, the date with the day of the week included, or the time given in the 24-hour clock. To add a formatted date or time placeholder to your clipping, open Clippings Manager, turn on the Placeholder Toolbar (Tools → Show/Hide menu), then from the toolbar, click Presets and select Formatted Date/Time
• For Sync Clippings users, there's a new option to only show synced clippings and folders on the Clippings menu. To activate it, go to the extension preferences, then under Sync Clippings, click Settings.
• Brought back the ability to redo an action in Clippings Manager. To redo an action (undo an undo), press F2.
• New option to add the date to the backup file name
• Many other fixes and improvements
