^{Originally posted by uniquadev April 20, 2024} Currently, when importing debug information with a pdb file, there is no pop-up window that allows you to toggle loading options. In my scenario, I have a pdb file that doesn't match the current binary; however, the types do match. It would be useful to have the ability to toggle some loading options..
