@Albert Margarit (NS Eng Lead) WebStorm: Faster than Eclipse, Code guide lines, you can contract and expand code blocks. Eclipse: Biggest Cons: - Eclipse is Slow with big projects. Biggest Pro: - Eclipse support multiple projects in the same main Widows in tabbed mode... (WebStorm does not support this and possible never will) according to Official forums users had been requesting this since 2015 or so...

(for me) the multi-project in 1 window isn't a feature i miss in the slightest. You can easily focus on 1 project at a time. if you want to open another project, just open one. It'll open it in a new window you can just flip between them. Its fast to open

When you work with multiple instances and you need to jump from one project to another for code review or changes is a big problem... ask @mattdahse

its not a big problem at all.. There's the toolbox app that opens them in 1 click

Yeah the toolbox app is key!!

Yep I highly suggest it.. super useful
