FH+ is awfully glitchy, the Ficho Caverns are a maze, and from what I hear, FH+ is pretty much dead. I say just stick with FH until FH+ updates.
Like you, I love the graphics and sleek interface of FH+, so what I did was that I copied all the textures from FH+ and pasted them into my regular FH. Now my FH looks kinda like FH+. If making pretty maps is what you're going for, but you don't like the glitches and crashing, that's what I would do.
