I think Whatsapp could improve in a few areas.
To start, Whatsapp still requires a phone number which is annoying. It would be nice to see them do email+password login and editable usernames. (like slack, ms teams, google chat, discord, etc)
Secondly, it would be nice to see the edit button made available forever, like slack, ms 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 for a more comfortable chat platform.
Another thing WhatsApp could use is better support for multiple devices. Currently you get one primary device and 3 additional linked devices. If you sign in to a new device without making it a *linked devices*, it automatically signs you out of your primary device and you may lose a bunch of data.
I think they should give users the option to let users choose what kind of system they want. I think many would prefer a more robust multiple devices system where we could login to many more devices than just the few that they currently allow.
Also, Maybe when you attempt to sign in, and you're already signed in to a primary device, they could warn you that you're going to lose the data that's not backed up on your existing primary device.
Another thought 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.
I think the ability to signup with email and password is good. Better multiple device support. Editable usernames so we don't have to share our phone number. There's so much spam out there today, we should be able to converse with people without sharing our phone number. The edit button needs to be expanded to allow editing forever. It's the principle of the matter. All other major chat platforms have it. The linked devices function is too limited and needs to allow more devices. Backup and storage should be available on the WhatsApp cloud/server instead of requiring backup and restore everytime.
