at the moment its sometimes not that convenient to edit lines that include names listed in the autocomplete.
additionally:
autocomplete should only set upper/lower case when the inserted command is complete.
example:
Try to name a Constant "#Sub_Division". when you type "sub",
the autocomplete will complete it to "#SUB" and ignore, that you will type further.
so you'll have to complete the new name, and then re-type the beginning.
I hope, that is not too complicated to solve...
I know, you, Freak, have a lot of work to do and a lot of serious tasks to solve...
but this little correction will optimize the conveniance of using the autocomplete..
