Because you ... no wait...
I demanded it, I've implemented a screen in OXCE+ that allows a player to check all the projects being researched at all the bases in one screen. Using the key "c", you can bring up in two places: Geoscape & a base's current research screen.
From this screen, if you click on a project in the list, it will take you immediately to that base's current research screen.
This is useful for times when you just can't keep track of all your projects. When you find yourself saying, "Now which base was researching laser pistols again?" or while watching the globe spin, "How much progress have I made over these past few days?"
Changes are located in my copy of the oxce3.5-plus-proto branch:
