### Original description

**What change would like to see?**

I would like a "Window" menu added to the menu bar.

**Why?**

Now that we can have multiple sketches open at one time this would make it easier to swap
between them instead of cycling through the windows one-by-one.

Would this cause any incompatibilities with previous versions?

No.

But this is mostly an issue when you have many sketches open which may be considered a non-
typical user scenario. However the "Window" menu is relatively common in desktop applications.

If so, how can these be mitigated?

N/A

Review the linked Google Code Issue 234 and its additional comments first, since the imported description says they contain more context. Then inspect the Arduino IDE 1.x desktop UI entry points for menus and open sketch windows. Done means an added Window menu lets users switch directly among open sketches without cycling through them.
