Instagram's current web-based version has certain limitations in terms of capabilities that users can do compared to its mobile app. More specifically, it's only possible to comment and like on desktop, while sending direct messages is only for mobile.
That could change in the future if a new report is any indication. Jane Manchun Wong, best known for discoveries of unreleased app features using reverse engineering, shared on Twitter an interface showing how Instagram Direct will look on the web.
Based on the screenshot shared by Wong, the web version of Direct may look somewhat similar to Facebook's Messenger. In addition, details about a specific message thread will show up on the right sidebar next to the conversation view. It will display the list of members in a particular conversation, for example.
It's not clear when and if this capability will roll out to everyone. Nonetheless, when it does, it will be a welcome change for users who want to interact with their friends with a bigger screen.
