@vaartis i thought of partial updates but i'm not sure whether it would help, since i would still need to traverse the entire tree anyway. One saving grace is that editor could use "light" version of the tree, i.e. just components themselves without taking the "placement" into account. I do intend on having editor be a "semi-minimalistic", with :marko: FULL POWER :marko: being accessible only through text editing (for which i'll make a proper PISS markup).

Another thing that might be slowing things down right now is that greentext colors are generated essentially everywhere even though it's unnecessary, mostly because there's no "Post" component yet.
