What about Smalltalk?

All your interaction with the IDE is implemented in Smalltalk. For each of the changes you want to preserve, figure out which UI class is used and browse the code to figure out how the UI class makes those changes. Then copy what the UI class does into a workspace script, save the script, and file-in to a clean distro image to check that it works.

Here's an example of a little script being filed-in to load a program, do clean-up and save the image:

i would want to preserve everything. this is not solvable with a simple script. in docker this feature comes built in. everywhere else all i need to do is copy my homedirectory, and every upgraded application works with the data i have. smalltalks design makes this a magnitude more difficult, and in the end not worth the effort until i get an opportunity to work on a paid project.

That's your decision to make and I have no reason to quarrel.
