Sometimes, when I do a find and replace, the text I want to find or replace may be longer than the width of the UI component and before I click the replace button I'd like to review that bit of text.
Unfortunately, the find/replace UI has a fixed size, meaning I cannot resize it making reviewing the text cumbersome.

search in the settings editor:

Of course, in sublime you have a very nicely sized find-replace widget

which, of course, can be resized even taller.
In next Insider, you'll be able to resize the find widget horizontally.
