Composition Tokens - improve readability of values within GUI widget

[skyw4kr]

Users want the ability to view the content within the value field of the token widget so they can make quicker selections.

Expectations:

• that the width of the Token and Value fields would scale evenly with the width of the plugin window
• expected ability to grab in the space between the fields and scale the fields horizontally
• expected ability to hover over the dropdown fields that are too long and get a tooltip that contains the entire value text
