3.4.8 is out, autoindentation fixed. (Franz).
One change I thought I'd mention:
Now you can type in a size for the font.
This is not type checked, but you can see what happens if you type in something wrong.
Now you can set odd sizes for the stc.
I need to set it so it recognizes the new size when you fire up the style dialog again (I will do so for 3.4.9).
