Reload tabs with matching URLs when they receive focus
Open extension's options after installation. There you can specify URLs to watch for focus.
Then extension will reload any tab with matching URL on receiving focus (when you switch to it).
If tab's URL has changed to non-matching — the extension will not reload it.
There is a general (for all URLs) threshold option: specify time without reloads for fast switching.
Examples:
* A site with recommendations like Twitch.
* A feed/board/forum like Reddit.
* An order/delivery page with tracking; if URL has order number — just use the wildcard (`*`).
