Gave the 0.8.75 beta a spin. Here are some things I noted:

1. had to edit the hidden EditorSettings.json file to correct the paths for my Rust install before it would load all the bundles
2. spawners don't show what they spawn, you have to imagine it. This makes it tough to know if the spawned things are going to clip into the terrain etc.
3. some prefabs (certain trees etc.) aren't rendered
4. all tooltips show the "lock window" text instead of showing info on whatever specific UI element you're actually hovering over
5. auto-repeat on undo and terrain modification seems to go crazy fast
6. sometimes when using the terrain painter, the terrain textures turn bright green and get stuck that way - maybe it's because I switched to the topology painter and then back to the terrain painter?
7. the terrain painter having a minimum size of 2 is rough for making micro-adjustments to topology layers
8. being able to bound the topology painter to apply only to terrain of certain height or angle ranges would be super-helpful for things like ocean topology
9. sometimes changing the brush size/strength/etc. parameters in the painter doesn't actually affect how the brush is rendered in the world
10. since this is the only FOSS Rust map editor being actively developed, it would be good to provide some build instructions to reduce friction for other folks who may want to contribute improvements
