Too bad the developer is an idiot. He refuses to add feature parity to the Discord side of things. He refuses to add a toggle to display nicknames only and he refuses to add a search function. He's focusing most of his time to the Slack functionality as that's where he's trying to make money off the software being shareware.
He claims that Discord users can't be converted to customers, despite nitro being big. He could easily add faux-"Nitro" features that BetterDiscord plugins add, such as the ability to use emotes from other servers by just posting them as an image.
But why give him money in the first place for a client that doesn't even match the simplest of Discords features?
