[FEATURE] Allow to create our "personnal" discriminant for OneKey/Triggers

Hello There !

First of all, i just wan't to thank you for all the work you made on WindTerm !
This software is just the best one in my opinion.

I don't really know if for you it will be bigs numbers, but i currently have 304 session configured, and my goal is to include every of the servers that i had to manage in WindTerm, and make my life better. something like 5/6k sessions. (almost 10 if you add an RDP feature in the futur)

to share my experience with you, i already got hard times to play with the Json, using Json to table tool, playing with filter to mass edit attributes. I think that i now got the trick so that's not an heavy need anymore, anyway it would be good idea to permit edition of selected sessions instead of only one.

My need today is to create a personnal discriminant that could be used to Enable OneKey/Triggers/Fast Commands display features

I got Some RHEL 5 to 9, AIX, Debians, etc.

OneKey can be managed by the Json, And i can be a bit cleaver on my triggers, but i feel like i spend à lot of time to check thoses switch

This feature would be appreciated.

Thanks !

PS : English is not my first langage so i hope that you'll read me easily !

The issue mentions session configuration, JSON, OneKey, Triggers, and Fast Commands, but names no files, tests, or code entry points. Start by locating how session discriminants and OneKey/Trigger display settings are represented, then determine the required configuration and UI scope. Done means a personal discriminant can be defined and used consistently by those display features.
