Support larger icons and icons with text labels

### Description

First, thanks for this project, a cross-platform Notepad++ is amazing.

One feature that has always frustrated me about Notepad++ are the tiny icons and there is no option to have icons with labels. I understand this is against the modern trend of "flat, colorless UIs" but often as you flip between many different programs (common in programming or engineering) having a labeled icon makes life much much easier.

Further, supporting larger icons is very helpful as modern high-DPI displays (1440p, 4K, etc) make these tiny icons meant for 96 DPI screeens very hard to see.
