Thanks for taking the time to write this up! ?
viet Custom pages: It's important for non-coder like me to create and edit custom pages. For Xenforo, I have to hand code the home page (https://m.ly) via my limited knowledge of HTML/CSS. I don't mind doing HTML, as long that the UI is good enough so I don't have to mess around with CSS.
I'm sure an extension will be created. It's not planned for core.
A clear financial roadmap of how Flarum developers will raise money, spending on testing/servers/etc.. so you guys can keep doing what you are doing and grow the community. This is important because a software can be there for the long term if it has strong financials. It's good for me to feel that Flarum will be there for a very long time, and you guys are not afraid to ask for financial help in the community.
More on that will come soon. ?
Planned for one of the next betas.
Uh, we're a forum. ?
What exactly would this entail? It even sounds too large for an extension - maybe building a bridge to existing wiki software is more promising?
Compatibility with CloudFlare (especially with their Rocket Loader bug). I know this is CloudFlare's fault, but somehow Rocket Load helps load site very fast. And I like it fast.
Feel free to open issues about the existing problems, we'll be glad to build around them.
Simple text editor: I recently learned Markdown language so I can somehow write it normally. But newbies wouldn't be able to.
Also coming in one of the next betas.
We're already compatible, someone just needs to write an extension / the configuration to use it instead of the file-based cache driver.
Working with external storage (AWS S3, Google Cloud Storage, etc...)
Same here, the code uses a filesystem abstraction already, it's just a matter of exposing / configuring the other adapters.
