One thing frustrates me and that's adding - border="0" - to images and tables. To get a "0" value you have to click to set to 1 and then back down to 0. Also having to tab to set values is a pain!
It might be useful to have the following values set to 0 by default, this will save thousands of clicks over time...
Table dialogue box defaults
- set cellpadding to 0
- set cellspacing to 0
- set border to 0
Image dialogue box defaults
- set border to 0
- put all options in one box and remove the tab
