how to expand DLL/SO/EXE file and add address to expanded space?

You do this with the Memory Map. There is a + button:

So why is this feature there?

The primary purpose of the feature is get your original program back out of Ghidra. You can make simple modifications to the binary by editing data and instructions in-place. I have used this a couple of times to alter the behavior of an existing program.

So are there other similar methods?

You'd have to explain what your goals are exactly for me to offer any advice.

For example, adding new assembly code to a program.

If you want to do that in Ghidra, you need to clear out some existing file-backed code, and puts yours in its place. You just have to get creative about where you store it. Keep in mind, this is not what Ghidra was intended to do, so you'll have to work for it a bit.

Are there other tools to add new areas? (Excluding paid programs such as IDA)

[ryanmkurtz]

Not that i'm aware of, but I am not up to date on what other tools are out there. We'd have to do the same googling at this point. Sorry!

Need more double register support for things like numbers that are larger than 1 register, proper segment:offset recognition, etc.
