Afaik, It appears the only way you see your researched modules is from looking at the Research tree.

Could there not be a toggle with simple a text listing of Tier researched mods, and available to research?

Basically include a text tab on the research window that shows available mods, exactly like the Kowledge Base tab that used to be in the Production Section of Player Profile. Far faster to navigate than jumping thru 6 pages of different tech to see if you have the production ability for a certain mod.

Apologies if someone else has brought this up.
Other than this love the new research patch.
