Whatsapp still requires a phone number which bugs me. I'd like to see them do email+password login and editable usernames. Also, I'd like to see the edit button made available forever, like slack, teams, google chat, discord, etc...we should control our digital footprint. People who claim that "15 minutes is good" - what do they think about slack, teams, google chat, and discord allowing unlimited editing. I don't think WhatsApp should be going for a "everything we type is set in stone type of platform". I think it should be a bit more casual and allow forever edits - not saying that's what people *should* do - but the fact that it's allowed makes me, and many others more comfortable with other chat platforms, and the issue is that meta kind of has a bit of a monopolistic hold on things and so sometimes I want to type things that are blunt like "no thanks" because, sometimes it feels like giving them ideas kind of "feeds the beast" but here I am, typing out some ideas.
Another thing WhatsApp could use is 2 primary devices. It's good we can link a few devices to our 1 primary device, and I can understand some security benefits of not just allowing *unlimited* primary devices. However, I think *2* primary devices could be a good happy medium that still balances functionality with security. This way, we could login to *1* extra device *without* having to *link it* to the *1* primary device. This would give us 2 primary devices, with 4 linked means 8 devices total, I think is good. Still not unlimited for better security, but one extra primary device would enhance functionality/accessibility.
But WhatsApp needs an ability to signup with email and password and allow 2 primary devices and hide our phone numbers when joining public groups. There's so much spam out there today, we should be able to converse with people online without sharing our phone number.
