Dunno, this feels awfully niche to me.

i would feel more comfortable if it also would address the problem in this thread: https://www.tt-forums.net/viewtopic.php?f=32&t=88400

Buoys have little to do with the topic of distinguishing between stations IMHO. It is rather a separate issue. There, in response to some player problem, I wrote a proposal to add transparency for each type of station, but I don't think that's a best solution. Maybe because I rather not need it, unlike hiding the buoy labels. :)
A much more interesting solution in that topic would be to differentiate the size of the inscription due the meaning of the station - the greater the significance, the greater the name (within reason). The smaller labels would have stations with a smaller meaning. Actually, that could also apply to the buoys. However, it seems to me a much more complicated change than the split of the transparency options.

But that's the entire point i'm trying to make. this issue is purely about your personal itch, not designed to help a broader audience.

I wrote how I see it, but it's rather not only my problem, since I often see in the game that players themselves shorten the names of the buoys. It is time consuming and yet they do it.

There is already an option to hide signs of waypoint/buoys in the settings dropdown.
There have also been idea to move them into the transparency options window, but no draft was convincing so far.
