Gigapixel 4.5 questions / file type, name, and output locations

In this version the ability to select a different output folder and file type (jpg, tif, etc) both seem to have disappeared. Probably a user issue, but … how do I change the file name, output type, and output location? I do NOT want to create a jpg from a jpg. Yuk. And I DO need to control what the output file is named and where it’s located. I’ve been through every option in preferences and the rest of the (sparse) menus, and can find no way to do it. Do I need to uninstall and reinstall?

PS – this bulletin board is a pain because it’s very random and I find it difficult to use. Grrr.

If you are using as a standalone the options will pop up after pressing Save
