Can I save the return address when producing an envelope in LO? In MSW this happens automatically, unless you check a box to omit it but in LO it seems you have to type the return address every time you need an envelope.

If you put a return address on your envelopes, it is likely that you use the same address every time. MSW saves that address and the template is pre-filled; if you want to omit the return address occasionally, just check a box (which stays checked until you ‘uncheck’ it). With LO, it seems that you have to type the same address for every envelope that you produce. I use LO for most of my work but still use MSW for envelopes and labels, as the LO procedure is so tiresome. MSW also retains the last envelope size and font that you chose; with LO, so far as I can see, you effectively start from scratch every time.

Please what is you LibreOffice version.
