KDE Connect is up high on my list of my favourite open source apps, because it makes transferring files between devices (PC / Steam Deck / Mobile) and more real easy. It's been around for a while now and the good news is that it's going to keep getting better.
Writing in a blog post, developer Albert Vaca announced they've been given a grant from the NLnet foundation as part of the NGI Assure fund, which will enable them to work on it full time.
Some of what they have planned includes adding in a mDNS backend for KDE Connect on all supported platforms, to improve device discovery and connections. Beefing up the security is going to be another area they're focusing on with dropping older encryption (that was used for older Android), upgrading various dependencies and ensuring all the latest security patches are in.
Plus they're also going to be looking at accessibility, to ensure the interface is as easy to use as possible.
Overall it sounds like the future of KDE Connect is looking great.
