Thanks! Will definitely aim for Windows and Linux builds in the near future. The app itself is built in ES6 on Electron and has virtually no OS-specific dependencies, so I don't anticipate any difficulty.
Also: If any enterprising hacker that uses Windows or Linux as their primary platform wants to volunteer to try building Tad on their platform, please get in touch -- I'd be delighted to have the help.
Thanks for pointing this out! Was due to some unfortunate scaling happening because the image was just slightly bigger than the CSS for the page would accomodate; now fixed.
Tough crowd! Code is not OS-dependent in any way; I just haven't tested or pre packaged binaries for these other platforms yet. Anyway, sources all on github; I would welcome your PR for other platform builds.
