some requests

Great editor, especially the integration with IMCE. Three feature requests though:

1)
It would be nice to have multiple 'returns' (ie. blank lines) replaced with < br >.
At the moment, if users want a larger gap than one line between paragraphs,
they have to enter the < br > tags manually.

2)
Is it possible somehow to allow users to choose different 'float' or positioning for
images, or some way of getting text to flow around inline images, without them
typing in html or css? Probably this is a task for IMCE, rather than BUEditor?
Also, do floats break the containing div (ie. the green border doesn't stretch
to accomodate the floated image)?

3)
It would be awesome if the html tags themselves could be in grey, and the
content text in black, to add a little clarity for unexperienced users.

And a slight bug:
4)
Everytime the preview button is clicked on and back-off, the text area gets
slightly smaller. After previewing twenty or thirty times (for instance whilst
trying to get some css correct) the text area becomes too small to use.
I'm using Opera.

Cheers.
