ISBoxer 1 isn't going to disappear or quit working when ISBoxer 2 is released. ISBoxer 2 relies on most of the same things ISBoxer 1 relies on.
I watched all of your Videos regarding ISB 2 … but i understood Maybe 5% of that what you tried to explain.
Until now i have configured everything by myself in ISB 1 and i dont know if it is possible to convert it to a ISB 2 Script without errors.
You have yet to see the big picture...
That's the thing some people don't seem to grasp here. You had no choice but to do everything yourself in ISBoxer 1, so you think you're going to have to build everything yourself in ISBoxer 2.
You're not expected to manually create everything yourself in ISBoxer 2, that's the whole point of Modules. If you're not a developer, you won't be expected to create Modules.
ISBoxer 2 is designed so that developers can make Modules that make configuration insanely easy for everyone else. So for example, with ISBoxer 1 people ask "How do I add large Character names to each window so I can tell which window is which?" and the answer is to point them at a complicated guide where they build this thing themselves (here it is:
http://isboxer.com/forum/viewtopic.php?f=27&t=2190). With ISBoxer 2 the answer will be "Just install the 'Large Character Names Module'". If it was possible at the time for Alge to make a Module instead of writing that guide, he would have made a Module -- and everyone would have instant access to the feature instead of having to figure out each step in the guide.
Additionally, I have to assume you're mostly referring to Hotkeys you've added in ISBoxer that you don't know how to re-create in ISBoxer 2.
I've not even demonstrated anything like what you did for ISBoxer 1 hotkeys yet so you're jumping the gun a bit here, but for the most part you're just going to be setting up Modules that support the type of Hotkey you want.
I can't count the number of people who come and ask, for ISBoxer 1, "can I just download a working setup"? They don't want to build everything themselves, it's complicated to do that. With ISBoxer 1 the answer is no you can't just download a working setup. With ISBoxer 2, you really will download Modules that set things up for you. You really will have access to per-class WoW Modules that include all the WoW Macros needed, and even include DPS Rotations. And if there's optional things, you can just tell the Module what features you do/dont want -- instead of having to create each piece on your own.
And again, this is why I am producing videos both for normal folks (which show how to install and use Modules), and videos for developers (which show how to create Modules, which involves WRITING CODE). ISBoxer 1 did not have ANY options for developers to do stuff like this, so I completely understand why that is confusing you.
WoW Addons make tons of things in WoW easy. ISBoxer 2 Modules will make tons of things in ISBoxer 2 easy. I don't expect you to code WoW Addons either.
