Some of us are using WebStorm/IntelliJ and others swear by Sublime Text. The SVG layout engine is custom built. The rest is pretty much vanilla Javascript with some JQuery. Feel free to ask us anything!
Are you using the latest and greatest Chrome? Also, this performance degradation may occur if you have many many other tabs open.
If the problem persist, there is still good news: try enabling the "Live resize of objects" checkbox in the "Settings" popover.
Great question actually - Once we were able to use Moqups to mock up the remaining dialogs, we started joking about Mockup Inception - Moqception. Really weird feeling, but also nice :-)
