Allow precise sizing by typing a value

[gingerbeardman]

It would be cool if I could type in a precise size.

Maybe by typing? Maybe using notches on the slider at preset sizes?

Example scenario is you want to size two symbols the same across icons.

Using the slider it's not really possible to set the same value by eye.

My current workaround is to duplicate the Symbolic icon file!

Makes a lot of sense. Thanks for the suggestion.
