Perhaps there is good reason not to.... but could there be a "File" menu option to import the same struct that is exported via the menu "Export FEA struct to MATLAB" option.
This would seem to accomplish the same thing as the two step process:
>> save path_to_my_model.fea fea -v7
...followed by FEATool Gui "File" menu "Load Model/GUI Script" path_to_my_model.fea
Perhaps a GUI option would make it too easy to mistakenly "pollute" FEATool with an illegal problem structure. And since there is already a two step method (above) to do this, which by is very nature carries with it a certain amount of caution, it may not be worth additional risk.
Kind regards,
