TL;DR
Ability to pin trigger technologies, like pinning an achievementWhat?
Pretty straightforward. Have the option to pin a trigger technology so that it's always visible.Why?
Currently, it's not simple to keep track of what trigger technology you're trying to work on, since if there's more than one trigger technology that you're making progress towards, it will switch between them. Also, if a trigger technology has a single event, like crafting a specific item, you basically have to memorize what the condition is. Trigger technologies also seem to get deprioritized in favor of traditional technologies if you're currently researching them.If you could pin the trigger technology, similar to how you can pin an achievement, it would make keeping track of which trigger technology you're working on easier.
This would be especially pertinent if a mod adds new and more complex trigger technologies.
