Sorry if I'm rude, but I think most of what you criticize is really unimportant for the game.
Seven or six crew members? I'm playing this game because torpedoes are a challenge - not to watch accurate numbers. Who is who in the control room is not really something I'm concerned with.
I typically load the game once every three or four hours I play. The fault damage message when loading does not bother me (scary the first time, but I guess we're all past that point).
The planes not working visually after hours of being submerged? Not exactly the thing that ruins the game for me.
I fail to understand why these post spawn periodically. If it was an appeal for a new patch I could understand it. Personally my annoyance with these minor issues does not amount to one tenth of the sheer joy I experience because of this game. Accurate way of setting torpedo data - yay! Risk of torpedo duds - double yay! The risk of getting in a Das-Boot type of situation where depth charges are just raining down gets me downright giddy! I guess people just have different tolerance levels for these things!
Frankly to me most of the things you mention do not take anything out of the appeal the game has. That being said I could do without the transparent crew like everyone else
