Hubs in search window is very very small

With the new options the search window seems to have very little space left for the "Hubs" option. When i have two rows of window tabs the Hubs are very very small (see attachment search_window-hubs.jpg). Maybe it's possible to add something like this (same attachment below Hubs) because it's not necessary to see the hubs. How often do you change them? So when i need to change them it will drop down and back when i'm finished.
