After remembering it yet again last night, I decided enough was enough, filed the roughest edges off of it, and posted it:
There’s not a lot of use to the internet at large in this tool (no one needs yet another IP Calculator), but the core of this app is written such that other screens/functions/pages/tools can be added to it. At some point I’ll get a wild hair to add something new and this frame will be available to do it.
One specific goal I have not set it legacy browser version support. There’s nothing in the tool right now that’s especially troublesome for older browsers, but I won’t much care if I introduce a problem in the future. The app is very specifically targeted at “the browser I am using right now”, and more loosely targeted at “the last version or two of the bigger browsers”.
There, I published it. Now I can forget about it again for another year and see if anyone finds it…
