I find myself writing norms in equations a lot, and sometimes need to have them lr'd sometimes don't. I think the plugin could greatly benefit by adding a config field to add types of brackets that are auto-enlarged. I picture it being similar to the custom trigger field, where bracket pairs can be inputted, such as \|,\|;|,|;(,);[,] etc. It could have default values for the regular brackets like the other customization fields, but would also add a lot of customization ability for specific use cases.
