Thanks for the response Lu. very helpful information when adding a "new" entity on the maker portal.
It doesn't however solve my issue, mines with an existing entity already added on maker portal.
What if I already have added an existing entity and want to add components (fields) to that entity? Supposing I'm worked on a minimal solution and want to add fields as requirements change, the requirements keep changing (agile).
I don't have the functionality to filter and search on fields on already added entities on the maker portal.
Also when adding a new entity there is no filter and the view for fields is different -
Custom solution explorer has the type and that is really useful for field information, however there is no filter (e.g. filter all "Option Set")-

New solution explorer has only Field Type no "Type" and there is no filter (i.e. I can't filter on "Field Type" or "Managed externally") -
