How do I research here? (SR1 player)

[Demented Mind]

New owner of SR2 and gifted my dad the game.

He hasn't started playing the game and I am doing 5-minutes session repeatedly to learn little about the game here and there. One thing I can't figure out is research. In SR1, research is always ongoing. In SR2, it looks like I have to click on something. I clicked on one but it said "queued" despite it is the only one in queue and not researching.

Also, am I right with my observation that SR2 research tree are researchable only once? In SR1, I can research, for example, Storage repeatedly to make ammo storage more efficient and more space.

Queued research will begin once you have enough research points stockpiled to start it. Until then, it'll just wait in the queue.

Also, yes, most research nodes are researchable only once. The WotH expansion and certain mods contain infinite progression nodes at the far ends of the tech grid, but those are the exception rather than the rule.
