I learned a lot by trying to pick apart what you do. There really needs to be a how to on add-on development, like Lisa is doing in the EE Blog with her bug tracker example. Seems like you have to do so much digging to find the most basic things out about how to put together an Extension.
I think I know how to incorporate MSM (loop through for each site id…which I think I saw in another one of your extensions…I had them ALL open, man!) - but I’m not sure I want to spend too much time on it with Add Sitename (EE 2.0 coming up, etc etc).
I also give you some link love on my Add Sitename page. I figure if I’m liberally reusing as much code as I am, the least I can do is point to your stuff everywhere I can.
I really like the addition of checking for updates. I think the next trick will be seeing if I can generate the version-check template dynamically, which I’m not currently doing. I have my add-on versions as their own custom field, so that shouldn’t be too difficult, I don’t think.
Anyway, thank YOU!
