Maybe it's just me, but...

When you have a D project that consists of a main .d source file and
separate .d modules, it would be great if pressing `Build` for the main
file would automatically detect the other files, like so:

`dmd main.d module01.d module02.d module03.d`

...which works if you just use the command line. So in Geany, there
could be a list of files that it keeps handy to check what the programmer
has for files, and then immediately take all the necessary steps to build.
Kind of like using the `-I` switch to import? But only now it checks by

Good idea or not?

Or is it already possible within Geany?
