When you open it, it immediately brings to your screen everything you have all lumped into one category. However its first question is about how you want it to handle widgets...transfer them to Nova or not. Well with everything jammed onto one screen (apps and widgets) with no distinction one to the next, I am not sure what action I should take to continue. Pick something....and it brings up a box asking if you want to use Nova, Touchwiz or something else and also asks if you want to use it only once or always. Well heck I don't even know what question it is asking me. Use Nova for what...use Touchwiz for what. I am sure this is all about how unintuitive Android is. Us new guys are simply going to have to learn the language of Android through use I guess.
quick help:
Yes, let Nova handle widgets.
And as far as all the stuff that Nova throws onto their homescreens - well simply longpress on it until your phone gives a short vibrate and slide it up towards the top of the screen and a "delete" box will come up. Just keep sliding it towards that in one smooth motion.
If you that "once/always" box that comes up? Lets put it like this. Lets say you're in Twitter and you tap on a link. That box comes up, and asking what you want to do with it. Open in Chrome? Open in Browser (Touchwiz stock launcher)? I always use chrome, but that's something you can decide. Cool thing is, if it's a youtube link or instagram link or something similar, it will open in browser - and then realize "hey, I have an app that can handle this rather then opening it in browser" - and it will pop up another box, so this time you can select which app you want to handle it and make sure you click always.
There are cases where sometimes you may want an app to only handle it once - so that's when you can use the "just once" option.
Simply put, if you're not sure, just try stuff - or come and ask for help, the forums are really great for helping people.
And if you realize you don't want a certain app to "always" be the default handler for something, you can change that back. Go to your phone settings, find your application manager, and then from there go the the app you don't want to be the default anymore. Tap on it, scroll down and you'll see "launch by default" and a option to clear defaults. Tap that it won't be the default anymore.
hope that's clear as mud
Remove whatever you don't want to keep. If you want to move something, again, long-press and slide it to whatever position you want. If you want to move it to a different screen just slide it to the side.
