Included in the release
New auto-connect feature added (thanks @neilenns). This is activated by default, but can be disabled in SETTINGS if one so wishes.
Caveat
This is working on my Windows 10 machine, with my network setup. There is a chance, however, that it will not work equally well on other version of Windows, or with other routers or firewalls.
Why is the download so large?
This single executable bundles the complete .NET runtime, so that you don't have to have it installed to run the app. This makes it easier for both you and me, so I think it's worth a slightly longer download time.
Problems?
If you experience crashes or other unexpected behaviour, please create an issue.
