While playing I came across a situation that I think could use a shortcut that would be handy.
On the Financial Dept Window / Features Tab it lists all the Features available in the game and their status with regard to different budget levels of vehicles. You can readily see which of these you have researched and which you have not. It would be handy if you could click on a listed feature (double click, right click, context menu etc. I dont know which is best) to be able to open the research tab to precisely where this research is in order to add it to your research queue.
Or maybe double clicking the grayed out checkbox could take you to the research tab. I suppose there are many possibilities to make this work.
