Today, application extensions in SPFx (command sets, application customizers & field customizers) can't be tested within either the local or SharePoint Online hosted workbench. This is a bummer and a big step backwards to such a cool aspect to the development story with SPFx.
I get that you need a list to work with, but at a minimum, the workbench could have a static list with static data and no other functionality for us to test the customizations on.
My wish is that Microsoft adds support to the workbench for extensions before GA.90 votes
Thanks for your feedback! We like your suggestion and we’re planning to build it.
Provide an onDelete() method that occurs when a web part is deleted from a page. This will allow for the web part to remove any files related to the instance being deleted.

Thanks for your feedback! We like your suggestion and it’s being added to our backlog. We don’t have yet specific schedule for this, but item has been added to upcoming plans for the SPFx and since request does make sense and has been requested from other sources as well, this will be most likely implemented.
I'd like to have the option for an admin to 1) load upp the script and other resources in a customer owned or managed CDN location and 2) allow the admin to specify that location when adding the .sppkg file into the app catalog.
This would allow for more flexible usage of SPFx applications and also allow enterprises to have better governance of the script resources - which would increase the adoption of SPFx and also allow ISV's to create more solutions.16 votes
