You should try posting the problems in the actual mod threads.

Anyway - i will have a go at some of them.

1 + 2. use the soan instead by clicking on the chart button. Or get the weps officed to id the target and the soan will open at the correct page.
You could try some of my tutorials to see how the stadi and other thing work.

3 + 4 not sure

5. no fix, but just use your mouse wheel to zoom

6. here i think you do get the effects (reduce sonar profile etc) but will only get the skin if you are in a type c boat. Looks like part of the hull is adding the skin

7. crew will not repair if the are wounded. Fixing damage takes time - click on your sub sytem page and click the item to fix - you will see a yellow hammer icon - give it time - things will get fixed. If you switch between them, it slows it all down.

8. ctr+z
