label dropdown or epic dropdown should show all labels without being limited to 20 items. Purpose: to search more easily and avoid creating duplicate labels.

Quick win. 

It would be a cool quick win to

1. remove the limit of items in the dropdown (labels, epics, etc). It took me a long time (years) to notice this. I am not a developer. I am a product owner.
2. Or create a "View all" button at the bottom of the list. 

In the skin of a user. And the problems that it generate. 

I have around 40 labels and around 30 Epics. 

When I do a search with the filter, I don't always find the right label because only 20 are displayed. So I have to remember the name of a label that I may have created a long time ago to write it in the field. 

When I want to assign an epic or a label to a new story, I can't always find the label or epic that fits best. 

I have already created some duplicate epics or labels because of this. This create a mess in my dashboard...

To solve this problem, I created an excel table with all my Epics and labels to search for them by writing them in the search field without using the dropdown. This wastes my time... 

The filter is a central element of JIRA. It allows you to avoid creating duplicates, or to easily and quickly find an old story.
