Resize capability for tab bar, toolbar, other UI elements

I know this will be a low priority as bugs and critical features are addressed, but I'd like to recommend that the tab and tool bars eventually gain the capability to be resized. I run a 4K non-Apple monitor and depending on the APIs used, some apps have very tiny UI elements which are difficult to read. You can change the text font size easily, but it would be nice to have that capability for the UI text and graphics which don't automatically scale. Notepad++ for Mac just recently added the option to resize the toolbar icons, so there is a precedent.

Great work on the app! My text editors of choice keep being abandoned by their developers and I have to keep switching, so I like the fact that this one is an active work in progress with a solid legacy.

At one time I looked at using SVG icons for the toolbar, thus allowing larger sizes. There is a nice remake of the original icons here https://github.com/Simandara/famfamfam-silk-svg

The first problem I ran into is Qt's SVG renderer does not always behave correctly so many of the icons did not look appealing.

I also started working on using ImageMagick to render each SVG as multiple sizes of the icons which came out much better. It took some extra code to load the various sizes, but ultimately don't remember where I left off on that.

Good point. I suspect NPP's developers ran into a similar issue as they only let you choose from several fixed sizes. That's an OK workaround, I think, but only if the required effort is reasonable. As it stands, the icons aren't too small and I don't use them enough for it to be a major issue.

On a different note, I'm very happy that the word wrap setting is persistent in NPNext. I edit free text quite a lot, and having it default to off every single time I open a new window in NPP is annoying.
