Sasak UI provide unique integrated components which aims to maximize user interface real estate with reduced development time while embracing the now relaxed styling customization in Vaadin Framework. We aim to provide a complete complementary UI framework for pro-grade application development. Consisting of Main Window with multi tab UI, which each dialog is contained within its own tab, in pursuit of pure multi tab experience under single browser tab. Of course, client-server communication is still centralized as normally on Vaadin App. So you can't hope to open another tab while waiting for the blue line to finish its job. I hope you can like it.
