I met repeat guest Nate Cavanaugh, Liferay's Director of UI Engineering, at this year's Devcon and he answered all UI-based questions that we could quickly think about - specifically with regards to Liferay 7.

As we recorded this on site at Devcon, you'll hear more background noise than usual - Auphonic did their best to clean the recording, and they did a great job.

Here are some of the topics that we talked about:

• UI frameworks get out of style soon. Can I still use AngularJS?
• Do I have to throw everything away that I have invested already?
• The YUI story and what its discontinuation means for AlloyUI
• Will AUI be reimplemented on jQuery? Is jQuery part of Liferay 7? What about different versions of jQuery?
• metal.js
• Lexicon, UI-Language, User Interface Guidelines
• Artifacts and Implementation of Lexicon
• Bootstrap, Bootstrap components, Atlas, the bootstrap versions in Liferay 6.2 and the components of it that are available.
• What happens when Bootstrap 4 comes out?
• Single Page Application, SPA, SennaJS: Go without full page reloads, largely by default.
• New Theming Tools - You can also use new tools in Liferay 6.2 (AYOR though). No more _diffs folder, pure frontend packages, themelets.
• What kind of themelets do we wish to have?
• We probably have forgotten something. Ask your questions in the comment section of this episode to be covered in future episodes.
