Well that probably changed in the last 2 years.
The caret is now a class of it's own, and the x position keeping is done
inside this class.
I am currently not aware of any setting in which it doesn't work as it
is meant to do.
I do admit that the amount of possible combinations of settings is quite
large, and that it is not necessarily always obvious how certain
combinations are supposed to work:
for example:
- Caret-past-eol = false
- trim spaces = PositionOnly
Trim spaces = "position only" means that pressing a space at the end of
line, doesn't insert that space (the spaces are only generated, once you
type some text behind them).
So space at the end of line works almost like cursor-right-key. Except
for that it is allowed to force the caret past eol (despite the other
setting). And yes, that is the indented behaviour.
The user has pressed a space, the user doesn't mind at which time
SynEdit actually inserts this space... Pressing space at the end of line
still has to work.

Which related components? Or are you speaking of codetool navigation?

In which way is the current redesign not working or making the IDE
unstable? Sure there were individual revisions that exposed some bugs =>
that is what it says on the label: current SVN is not a released version...
Except for, if you do not like extra windows, you do not use the feature
=> that still means the IDE is working and usable.

Options / codetools / general
And yes there is a point => the indentation settings are hard to find /
spread across to many pages....
