Never mind, we all want to be heard. I do not know if you have been using other messengers than Delta Chat, but my personal impression is that a messenger must be a “geek toy” nowadays to be attractive, especially to younger generations of people. The developers are working very hard to cope with some challenges our classic mail system “provides” to them. They basically have to find ways around limitations, while other products often rely on a newly created technical basement that is more flexible. But - and that is a huge advantage to me - Delta Chat is a good example of “backward compatibility”. It is a tool that can be used to communicate with anyone who owns a mail address, messages do not even have to be encrypted.
AFAIK, this has been discussed already, and I think we are not that far away to have this feature in a future version of Delta Chat, but that is something the developers certainly know much better than I do.
Much more important to me is the stability of Delta Chat, and I have been able to observe continuing progress towards that goal. (You can see what is going on in the respective Github repositories, how many huge and tiny improvements were made, and how enthusiastic the development team is. I have never known a team of a higher commitment than this one.)
But I have to admit that Delta Chat is not for everyone. After all, it is a messenger, not a classic mailer. You may want to have some features in Delta Chat which you are used to have in a MUA. The good news is that there are ways to use both kinds of these apps together, just as you like.
This forum section is the right place to be heard when talking about (new) features, considering that users can be so much different. The more people demand something specific, the “louder a voice” can become to enhance Delta Chat the way it should be.
