update in editor doesn't save before build

[roblamoreaux]

Describe the enhancement

A few times I've made some changes in the editor then pressed update, only to find the changes aren't in the updated node.

I realized it had not saved before building.

I think it should at least ask to save changes before building.

Then it could be a bug and it didn't realize the file in memory was dirty

Use cases

No getting confused that your node doesn't have your changes

I have noticed this too - Prior to 2026.6.x it would save when "Install" was pressed.

This was a bug that was fixed in the version bundled with ESPHome 2026.6.3+

I see 2026.6.3 just arrived in my HA - YAY! :)

I have been programming since FORTRAN-2, and no IDE that I have ever used would not do an automatic save before compile.

You make edits to a configuration and click on "Install", how many iterations of "edit" - "install" will it take for a newbie to realize that the reason his edits don't seem to be doing anything is because THEY ARENT IN THE FILE JUST COMPILED!
