QoL: Highlight line of text of your chosing

I had an idea for a QoL feature. Make a text field where you can put in any line or lines of text. These lines will now be highlighted wherever they appear in game. Some remnant you want to be aware of in Expedition, no problem. Some map mod you cant run, no problem. Some altar mod that gives divines, never miss it. Some mod you want to alt-spam on an item, there you go.
