When using "new file" in the a mixed project, only C files are shown(in VS2019). While one can change the extension to .d, in D projects it allows one creating a d file.

Also, cannot drag or add folders(when going to add then new folder, it is grayed out). This is for a brand new mixed project.

and build time and reason are not shown even when checked in the tools/options.

You can create a new D file without associating it with a project (Ctrl+N), and then move it into the project.

But I'd like to add it to the "Add New item" dialog, too. It might have to invade the C++ branch of the selector, though.

As this is a VC project you will have to ask Microsoft why they don't support this functionality.

Having to setup all filters for a subdirectory structure manually can be quite some pain (and doesn't work with wildcards).

Again, this is a VC/msbuild project (that's why the options are in a
".visualdproj" section).

You can enable verbose msbuild output in the global "Projects and Solution->Build and Run" options and try to decipher the logfile, but it can be pretty nasty.
