Like the title says, the "Browse games" server list isn't manually scroll-able by pressing and dragging the left mouse button even after the list has fully loaded and updated. The mouse wheel works fine but
lags behind when there are many servers that try to load in simultaneously, so I think allowing to use the faster LMB variant would be great.
(Yes, I am actually clicking and dragging in the .gif, you can't really tell but trust me on this one)
EDIT: Clicking and dragging the LMB doesn't work with any filtering option. I can only assume this functionality isn't in, and if it is it's simply not working properly.
