It's now live for real https://extiverse.com/extension/kilowhat/flarum-ext-custom-paths
This is my first "simpler" premium extension. For these kind of extensions, I use a low single payment. Just like with the bigger extensions, you will get updates and email support all the way to Flarum stable and most likely beyond.
Sad truth: this extension took way longer to develop than I anticipated. The FastRoute router is awesome.
Feel free to request compatibility with additional extensions. I've added the most popular. I will add support for the profiles sub-pages later, together with integration with my other premium extensions. The SEO extension is not compatible and I'm not sure compatibility is possible without a refactor of SEO (SEO reads the URL, not the route name...)
Also before anybody asks, accented letters in URLs cause havoc. I found a way to make it work on Firefox, and then it broke on Chrome. So it's not implemented until I find a proper solution.
But it works very well for simple changes 😃
