Would be great if the block and entity would glow, in the same fashion as Vanilla Pings
The glowing effect could come in addition to the icon & distance display, and could be disabled from the mod's settings.

Example from Vanilla Pings :

For the record, https://github.com/YMGPwcca/PingCC which is a fork of PingWheel has this feature too

Highlighting pinged entities through walls is probably a good idea, though I'm not a big fan of the vanilla glow effect.
I also have to look into how these effects are applied, since our channel feature requires this to be client-side only to limit the effect visibility to certain players.
