I'm not sure I'm there with such an option. I see how it can provide quicker access to selecting a board / port, but I'm not sure how often I'm picking a different board for an INO. Most of my code is board specific (my Teeny-based INO's with ILI9341_t3 will not compile on a NANO).
What I do struggle with is the board not begin remembered for each INO. I open my IDE and the board defaults to the last chosen board. I generally have 3 MCU's I'm coding for Teeny 3.2, Teeny 4.0, and an ESP32 (rarely Arduino's but on occasion). Each sketch is board specific yet I have to chose the board every time I open an INO. This option will make that selection easier, but it really shouldn't be needed at all if the board was saved with the INO.
Imagine this open ino, change a line compile done as opposed to open ino, change a line, compile, get a board warning error, change the option, recompile...
