Shift+Enter problems

As far as I know GB has always had this problem with line spacing. When you enter after a line it leaves quite a lot of space between the lines of text.
E.g.
Example line 1

Example line 2

To combat this you can shift+enter/return to make the following line appear directly below the previous one.
E.g.
Example line a
Example line b

Sadly, using this method seems to cause a lot of problems. Whenever you edit a message which has shift+enter spacing in it, it will revert to the larger spacing.
There are bigger problems as well. Here is a particularly annoying example:

As you can see the "RE:" part should not be next to the Fatal Fury link but on a fresh line instead. But when I try to edit the post to fix this I get this:

In short: Is this a bug or is there simply no good way to avoid these massive gaps between lines of text?
Is it a problem on my end? I would love for this feature to work properly or for the line spacing to be the closer one by default.

Thanks in advance.

P.S. The "uploaded images being very blurry" also still seems to be an issue.

@hassun: Indeed. The WYSWYG has a few problems with whitespace (among other things).

Will try to take a look at this, can't guarantee anything super soon though.

As far as the blurry images are concerned, that's related to a quality setting on a specific size. Will look at that too.

Thank you kindly.
