@sosnovsky @ioanmo226 Let's discuss the encrypted messages pattern for a conversation. Please look at the above comment where I've collected results for different clients.

terminology

reply - text that a user typed as a reply
quotes - text that contains preview replies
signature - user's signature which is usually appended by an email client at the end of a reply

Generally, we have two different approaches.

1. reply + quotes + signature
2. reply + signatures + quotes

As you can see we have the following situation:

• Gmail uses 1-st option
• FlowCrypt Web uses 2-nd option
• FlowCrypt iOS uses 1-st option in combination with 2-nd option(maybe a bug)
• FlowCrypt Android uses 2-nd option

It will be nice to have the same format for all FlowCrypt clients. As for me, 2-nd is simple in realization ))
