Ok a new 'rehearsals', version 2.86 are available here:

Changes:

1. Have returned by to writing fraction as , and similarly change to to etc
2. Were tidied up the integral and sum operators also, then now insert just the minimum required code.
3. With is now written as f. This is to be more inline with established conventions in word, excel etc.
4. When you click an icon on a panel it will automatically close after about 1 second. This is help avoid confusion when people click an icon, but don't see the new code entered in the panel below, because the panel is obscured the main box.

Thanks for the continued suggestions. Will
