the "use" field is used to restrain a button until a requirement is met
the "show" field is used to show/ hide a button. this is what we will use.
make a new requirement from scratch, so both fields should be blank
add a node in the "show" field, then change it to a "not" node
add another node branching off of the "not" node, and make it "count upgrade"
modify that node to have the alias: (your upgrade) and state "queued or better"
apply requirement to the upgrade.
Observers
observers are enabled by default. go to the map dropdown menu in the top left and then open "map options" find the checkbox for "disable observers" and uncheck it. this will re-enable observers.

you use requirements to remove the buttons of upgrades after they are researched.
observers... never had to do that. I believe its somewhere under map or player properties
