Export Tab
Two columns: 3D Mesh Formats and Image Formats, each choosing which formats a save dialog offers and which one it preselects.
3D Mesh Formats
Each of the 8 curated formats gets a radio button (picks the preselected default) and a checkbox (enables it at all), both greyed out if your edition doesn't include that format — see Formats & Edition Availability for exactly which editions unlock which. A checkbox left checked from a higher-edition settings file can't put a locked format back into the save dialog on its own; the actual gate is enforced independently wherever export happens.
Image Formats
JPEG, PNG, BMP, WebP, JPEG XL, OpenEXR, Targa, IFF and TIFF each get the same enable/default pair; PNG is the only one on by default. JPEG and WebP add a Quality field (1–100); PNG and TIFF add a Compression field (0–9, higher is smaller and slower) and a 16-bit checkbox.
JPEG XL also has a Quality field (1–100), and at 100, its default, it is lossless: every pixel is kept exactly, and a 16-bit image (a painted height map, say) is written at its full 16 bits — usually a good deal smaller than the same image as a PNG. Below 100 it compresses like JPEG, only better. It needs no extra build options and is in every edition.
16-bit output needs two things at once: a build compiled with OpenImageIO support, and Ultra edition — without either, it's disabled with a tooltip explaining which one is missing. When available, it forces genuine 16-bit-per-channel output, upsampling an 8-bit source into a wider container rather than adding detail that wasn't there.
