What do you think about adding the vanilla trees to the startup text setting as defaults? Most of them are much taller than their hitbox and I was surprised that the game didn't have them toggle-able by default with the introduction of the "tall" feature. They seem like a perfect use case for it.

I've compiled a list of those I think deserve it the most if you're interested:
tree-01, tree-02, tree-02-red, tree-03, tree-04, tree-05, tree-06, tree-06-brown, tree-07, tree-08, tree-08-brown, tree-08-red, tree-09, tree-09-brown, tree-09-red, yumako-tree, jellystem, tree-plant, slipstack, funneltrunk, hairyclubnub, teflilly, lickmaw, stingfrond, boompuff, sunnycomb

I decided to also list the Alien Biomes tree names for reference, if you or anyone else wants to add them:
tree-desert-a, tree-desert-b, tree-desert-c, tree-desert-d, tree-desert-e, tree-desert-f, tree-desert-g, tree-desert-h, tree-desert-i, tree-desert-j, tree-desert-k, tree-desert-l, tree-desert-m, tree-desert-n, tree-dryland-a, tree-dryland-b, tree-dryland-c, tree-dryland-d, tree-dryland-e, tree-dryland-f, tree-dryland-g, tree-dryland-h, tree-dryland-i, tree-dryland-j, tree-dryland-k, tree-dryland-l, tree-dryland-m, tree-dryland-n, tree-dryland-o, tree-grassland-a, tree-grassland-b, tree-grassland-c, tree-grassland-d, tree-grassland-e, tree-grassland-f, tree-grassland-g, tree-grassland-h, tree-grassland-h2, tree-grassland-h3, tree-grassland-i, tree-grassland-j, tree-grassland-k, tree-grassland-l, tree-grassland-m, tree-grassland-n, tree-grassland-o, tree-grassland-p, tree-grassland-q, tree-palm-a, tree-palm-b, tree-snow-a, tree-volcanic-a, tree-wetland-a, tree-wetland-b, tree-wetland-c, tree-wetland-d, tree-wetland-e, tree-wetland-f, tree-wetland-g, tree-wetland-h, tree-wetland-i, tree-wetland-j, tree-wetland-k, tree-wetland-l, tree-wetland-m, tree-wetland-n, tree-wetland-o

Additionally, I've discovered that trees weren't made tall by default due to a limitation of the current shader used by the "show animated trees" setting - they are only hidden correctly with it disabled. Not sure yet if that'll be fixed, see: https://forums.factorio.com/viewtopic.php?t=136734

I think making it the default is more confusing than not, but thank you for documenting the options for those who would like it.
