I think adding an autosave feature for retool would be great. I have had many times when in the middle of coding something i lose the connection or have a restart, and then all the work i have done is gone, up to the last time i saved. VS code has a autosave feature that will save your work as you go. Another coworker suggested even something that saves the state in a cookie or something, and if you lose your app, it will bring you back right where you were at, and no loss of work.
I was looking for something similar, but on the user end -- like when typing in a google doc it will just autosave your text as you type. We have some long text fields that users can type in and want them to be able to leave and come back without losing their work or having to hit 'save'
