add a title for indexer 'enable' checkbox column?

[OneCDOnly]

Hello,

This morning, I finally worked out why Watcher3 hadn't been getting any results from NZBHydra2. It's because I hadn't clicked the checkbox to the left of the indexer:

This had been driving me crazy as the "test connection" button worked, and a manual search via NZBHydra always returned results. 😁

There is no on-screen indication as to what that checkbox does. When un-ticked, it's just an anonymous grey box.

Can we please add a column title called "enable" or "use this indexer" or similar to explain it?

Thank you.
