IDE does not place board info in INO file

[oldmanegan]

This is a persistently frustrating issue. I searched the issues list and did not see it, my apologies if this is a repeat of another's input.
Issue: The INO file is defined to not be board/MCU specific, great; however, when working on a project involving multiple MCUs with multiple INO files open, this flexibility is a severe drawback.
Use Case: Developing a Smart Home app involving 3 systems - one with a 328, one a 1284 and one a 32u MCU (different MCU to meet a different need). I am troubleshooting the final programming/operation and running into the need to stop and switch boards and related info when switching to a INO for a specific system. A pain.
Request: Why can't I set a Preference in IDE to "stamp" the start of an INO file with the related board data to automatically be loaded and set by IDE when a specific INO has the focus? Or upon a specific key press? IDE optionally should be able to be told to ignore as well...
Requirement: Board data must include board type, clock (the 1284 is running at 20 MHz), and JTAG info.
Let me know if you need more info...

Well, this is an old suggestion...I've only found this issue #5121 , but I remember having read this many times (maybe in forum).

I like the concept of making each sketch "separated" regarding each one's related hardware, instead of the hardware being a global setting in the IDE. If a "Window" menu item is created to enable ease of selecting the active project sketch (since tabs are window/project specific), then in the window domain information stored by the IDE could be the last selected hardware for that project sketch window. Make sense? Would "kill 2 birds with one stone" give a fast way to move between open sketches/windows and retain hardware info per.
