Thank you so much! I'm happy to get any input about the topic, it's kind of hard to get answers about these specific traits.

A lot of the photos on google for M. Borsigiana show less mature looking leaves with less inner fenestrations, however I do see text mentioning that the inner fenestrations are possible. I guess most people just don't have the lighting to get theirs to grow leaves this size?

I'm not sure how old this specific plant is but I usually cut my plants back pretty often and I made a decision to leave this one alone to see how big it could get... it's not as happy as it could be admittedly but I'm trying to make some accommodations to fix that.
