Guide data overflowing, Can I easily hide most, or preferably, all channels in a source?

[jsfullam]

Hi,
Several of the free sources we can add have hundreds of channels each. It seems that adding so many channels generates a tremendous amount of guide data. The server seems to handle it fine. Evidently, the clients can be overwhelmed with too much guide data.

The problem I am faced with is that, when scrolling the guide too far ahead in time on a client, I eventually hit a memory overflow error resulting in a crash. Depending on the number of sources and channels I have added, this can be a period as short as 24-48 hours.

I am told that hiding channels through the "Manage Lineup" interface will keep them out of the guide data. I'm not looking forward to clicking what may be hundreds of 's to wean down to the very few channels I care about. Is there a way to easily hide all the channels in a lineup, and then, only un-hide the very few I really want?

Or, can someone please put together a script to hide all channels on a single, or even multiple sources?

Perhaps, if it's a useful thing for many of us, maybe this could be an added feature to Olivetin? @bnhf ?

Channels Helper bookmarklet for working with Manage Lineup

Since we can now add all these awesome TVE and m3u channel sources for things like Pluto, Plex, etc., I've found myself struggling to manage the hundreds of channels often listed in the Manage Lineup dialog (Admin Settings website \ Sources). I decided to try to throw a little javascript at the problem last night, and wound up ultimately settling on a simple Bookmarklet you can use to do things like Block/Unblock all, Fav/Unfav all, sort channels by name, sort channels by number, etc. It adds …

Thanks for pointing me in the right direction. That is Exactly what I needed! Initially, I was intimidated by a lot of things I had never heard of...Bookmarklet? gist? Huh?

However, even though I have no idea what I'm doing, I managed to muddle through it and get the Bookmarklet working. I guess that this old dog can still learn a trick or two.
