The developers over at KDE Connect are working hard to bring us new features. One of the most promising and useful, from my point of view, is the SMS App.
The SMS App allows you to filter all the conversations, and when you select a thread it loads the thread and displays it in the desktop app.
You can then type your reply and click on Send without having to unlock your mobile phone! Also, if you have an image saved for the contact it will display this in the thread list.
I am really looking forward to the next release of KDE Connect which will have all these shiny, new features 🙂
