Is there any plan to access Aether thru a web browser?
Not for now, since Aether is a P2P network, it does require an app to be installed, so that other computers can connect to you.
However, we’re building something that allows people to host their Aether nodes elsewhere, and connect to them. In this case, you could host your Aether node that way, and just connect to it via https. This is still in progress though.
Does that mean you can also have an Aether web interface on your computer and access it through https://localost:[insert some port number here]?
Yes that’s the idea, accessing it via browser, or putting the desktop app into a special mode that uses a remote backend instead of the backend it comes with built in.
