Add support for text in slots to Explorer

[bheston]

What feature are you requesting?

Currently in Explorer it's possible to add "Text" elements as the content of a slot, say for a fast-button, however it isn't marked to appear in the correct slot.

What would be the benefit of adding this feature?

It makes the tool look like it's broken. We should wrap it in whatever is necessary to make it appear in the correct slot.

What solution would be ideal for you?

Possibly wrapping text in a span, but anything that works is fine.

Slots with "Text":

Slots with fast-badge:

In order to do this we should:

• Ensure we cannot add text to any other slot than the default
• Create a configuration for the span (and other elements) so that when added there is some content
