In regards to icon organizing, 5x5 and moving/placing the icons where ever you desire, is it necessary to get a combination of any of these? all of them? or will 1 do the job. 3 out of the 4 are paid and I'd prefer not having to buy all three, but every time I research the difference, some say there isn't much other says there are (but never list the actual differences). So what's recommended for just icon organization, 5x5 and moving icons to certain spots that are not limited to the default grid? I'm on an iPad mini and ultimately just want my icons to stay in place when changing orientation and have some in different places to make room for widgets. Also I noticed a lot of themes essentially have this format already (at least from the screen shot) are these only doable if I already have one (or a combination) of the apps listed above? or when installing certain themes they come with the format right out of the box type deal?
