The ghost placement sound is not only annoying, it literally makes me physically uncomfortable - like screeching on a blackboard. While this might be related to individual perceptions, all others I play with feel the same way.
Contrary, the entity placement sound has become very quiet related to other sounds. I have become very reliant on hearing this particular sound for confirming face-paced actions and counting rows of entities while dragging. Consequently, this forces me to increase volume.
Some of the sounds just feel very redundant, in particular the UI sounds. I counted 6 different *clicking* sounds spending a few seconds in the options menu. That feels like a fresh installation of Windows 95 - I distinctly remember disabling sounds was one of the first things after a Win95 installation was to disable them. I thought UI design evolved beyond that by now

When it comes to the icons, the electric miner icon stands out. While I don't like the look, that matters much less that the fact that it's very had to distinguish from the burner miner. Imagine explaining to a friend who's just picked up the game which miner to pick. This is not an issue with belt, inserters, or assemblers.
A general thing I noticed with the Icons: For me (1440p resolution) the UI scale defaults to a very sensible 125%. However, the Icons don't seem to be quite as crisp at this scale than at 100% or 200%. I feel that may be quite a common default scale, so it would be great if that could get some love too.
These things stand out as needing to be addressed to me. Some other changes, I don't like, but I would give a try getting used to before really criticizing it. And again, overall this is a good step towards a polished game.
