fix #73

[fenos]

This is really nice!

One small change before merging this would be to group the about files on it's on folder to keep things tidier.

I'm not too picky on a folder name but something like about - nativeUI or something logical 😄
other than that this is great.

Thank you!

@fenos updated. I feel like my bundle of the assets for prod is very messy.

I'm only just learning the Electron ecosystem... Do you want to accept this PR first and we can refactor it later?

For future reference:

1. use type script & react for rendering
2. use webpack internal bundling for the icon image
3. less branch for checking process.env.NODE_ENV or HOT

@jackielii Thanks!

Yes, i think for now it's pretty good and simple enough for future changes if needed

Well done!
