Improve Showcase

[mgrouch]

We are considering to migrate from Sencha GXT. Their showcase is much better through
https://examples.sencha.com/gxt/examples/

Can KVision Showcase be improved?

Thanks

Of course it could be improved :-) We are open to contributions ;-)
But please remember KVision is 100% free and open source. Sencha is commercial framework developed by a corporation.

Jmix also has a nice "Component Sampler" which includes code samples plus documentation. Just dropping the link here for reference https://demo.jmix.io/sampler/

(I just started reading Kvision's Guide so it's a bit to soon to even consider taking on this task!)

Maybe duplicate of #33, though this (#366) has a better description & title (more focused) IMHO.
