Xenobotanist here. I've been submitting numerous bug reports on the git, and am very glad to see the dev's have been dealing with them quickly!
My suggestions/recommendations will be mostly focused on the xenoflora area, but a few for science in general.
1) The Xenofloral blisters should be made of something stronger than just reinforced single glass panes. I think it would be wise to either set them up with that reinforced pink glass (can't remember the name of it off the top of my head) or change them to be the usual full tile sized windows so you can put emergency shutters in them, both to close in case of carp, and to close in case you wanted to grow plants that need dark environments. (I definitely prefer the Shutters option, even if the windows are technically weaker because of it. )
2) Make the walls of the Dangerous Xenoflora Area Reinforced Plasteel. That area is supposed to contain the VERY DANGEROUS plants, such as ones with potent acid or dangerous reactions, and steel walls can be destroyed by such plants very easily.
3) There is a small room that separates the R&D lab from the science hallway, and it currently serves no purpose, other than being a blindspot for the AI.
