Title: I&#x27;ve a Visual Basic application at hand which served its time and still going strong in a productions setting. But changes to the logic are  expectedly difficult with UI and business logic completely intertwined. And also, if I want to put it on cloud, this architecture is going to fall off. For the above two reasons, I wanted to upgrade this into a modern stack - and an obvious choice was to - Javascript based UI, with any DB to support (postgres) and a queue or app server to service this.<p>My question is: None of the web style solutions seem to be suitable for a keyboard based (tabbing style) grid to represent an itemized billing. I was able to see some Kendo or dojo etc.., but most of them have a mouse based &quot;Add next Item&quot; button , which is not suitable for a fast paced billing application. Any suggestions within or apart from web based frameworks should I look at? Or should I fall back to some systems programming language (C type) with Qt kind of solutions?<p>Thanks for your suggestions in advance.
