Exporting
Exporting is done by clicking on the Export button:

Then choose whether to export to [AZUR], BMP or a BMP Thumbnail:

For example, clicking [AZUR] will export the visible drawing to a [AZUR] file. Naming a file without a dot will export to a [AZUR] image that has the same name as exporting the file name with a dot. For example, 1-2.soni and 1-2 will both export to 1-2.azur:

If you want to, you can export to a BMP or BMP thumbnail. This is useful for programs that don't have [AZUR] support.
If you want to export a transparency, so that all white (0xFFFFFF) is transparent, click on the Alpha Mode button:

Then click Export again. Clicking Export again will overwrite the previous export of the same option. This is where renaming files come in handy:
