UPDATE: resolved by 6b32e79

I think the **Tools** menu item should be retained for some time to make a gentle transition of this important part of the IDE's UI.

The current menu path is very frequently mentioned by the community members who provide volunteer support to the beginners who invariably share code that is unreadable due to atrocious formatting.

For example, this is the Arduino forum's most important document:

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966

It contains four mentions of the current Tools > Auto Format menu path.

I'm with @per1234 on this
The item in the Tools menu should stay for a transition period TBD.
During the user tests Gianni and I ran last year every user was looking for auto-format under the Edit menu.
I prefer redundancy (we're not new to it, see "Manage Libraries") on the path to a better future :D

Please add it to the Edit menu but don't remove from Tools

I missed the comment of @ubidefeo, here I've restored the Auto Format item under the Tools menu.

Auto Format is now present in both the Edit and Tools menu.
