Update?

I’m wondering exactly what benefits I will get by upgrading to 2.3.
I really have no need or interest in the new “tagging” feature, and most of the other items I see in the upgrade description are either above my experience level to use or un-needed entirely.

My main problem with my current install is the management of posts section – specifically the editor.

I switch back and forth between the visual and code editors to see what my posts will look like. The problem is just about every time I edit a post the code changes from what I enter and screws up the whole look.

So – is the editor function of the new version “fixed” to not do this? If not I really see little need for me to upgrade unless there are other bug fixes I didn’t see.

Also … I use Platinum as a base for my blog, with a few edits here and there. Will this template work in 2.3? Doing the upgrade, can I just overwrite the “styles.css” and “r.sidebar” files in order to retain all the additions I have in the right sidebar?
