"path for new file" textbox is not wide enough for some file names and it doesn't highlight selected text

Hi,

First of all, I would like to thank you for making this minimalistic theme. I really like it. One issue that I regularly face is this create new file issue. The textbox for entering name is not wide enough for some names, especially when the font size is large. Also there is no highlighting when I select text in this textbox.

I would also like to know what are the plugins that you use. Finding syntactical bugs is hard while using such monochromatic themes.
