If you slide the slider clear over to the right, you can get a fairly decent view of tip, stroke, and name, plus the additional info. You won't see very many brushes at a time, but I find it a decent trade-off. If you turn off stroke and name, you can see quite a few tips at once. It looks as large as in the Preset Manager on my monitor.
I'd like even bigger, but then, I do always find I want more. <g> . . . I still really want a way to mark favorites like I can with fonts. I don't want to take them out of their sets, because the sets are based on type of brush, so what I want are favorites within the set. But this is nevertheless very, very good compared to being stuck with just the Preset Manager, like all my other Presets still are.<sigh>
