Thanks for the heads up! I pushed a fix and drag-n-drop should be functioning properly again, sorry about that.
Linktree was definitely an inspiration to recreate - the big differentiator between Memlink and Linktree (and pretty much every other competitor in the space) is that, Linktree requires you to be connected to the internet. Once you've loaded Memlink once, for any page you visit first, you can load any new Memlink site entirely offline (granted, dynamic blocks like the Tweet block will show an offline state until you're back online). This is because the block parser and renderer is cached once you've loaded it, and Memlink operates as a PWA and can still render content without hitting a server. You can try it out on your end by:
1) Make sure you've gone to meml.ink at least once on your phone
2) Create a new site using Memlink on your laptop or desktop
3) Put your phone in airplane mode/disconnect from WiFi etc
4) Scan the Memlink QR code from your laptop/desktop onto your phone
5) The Memlink page should load fine on your offline phone
This could be hugely useful for a variety of reasons such as limited access to internet, limitations on bandwidth usage, resiliency for important documentation/info against network failures, censorship, last-mile connectivity, etc.
