Force gallery navigation arrows to always display

[jayzambrano]

Hello and thanks for this library, it's always a great solution!

I see that the rendering of leftArrowBtn and rightArrowBtn depends on the 'supportsTouch' variable. I have a scenario on mobile where it is not obvious to the user that there are more images, so even though the device supports touch events, I would still like to display the previous and next arrows. Is there an option to achieve this?

I don't think so. If you want to make a PR that adds an arrows option and updates the logic for displaying the buttons then I'm open to merging that.

Otherwise I recommend checking out bigger-picture, which does show the arrows by default and also lets you pinch zoom on mobile: https://github.com/henrygd/bigger-picture
