Hey OP, nice launcher. A few things:
Someone else mentioned it here, but the wallpaper isn't positioned correctly or is stretched/not stretched enough, I can't tell. Here are direct screen shot comparisons of Apex (left) vs. Nova (right). Look
closely at the wallpaper positions, you can see they are different:
Also:
-Can we have editable homescreen and dock margins like Nova? They give you I think 4 margin options each.
-Most times when I activate the homescreen previews by any method (gesture, pinch, etc), some or all of the homescreen preview boxes will be blank except for the dark background rectangle shape that makes each up. I've rebooted and everything and almost every time, at least the bottom two or three out of five screens are just blank rectangles.
-Also, relating to the homescreen previews, can these be cleaned up a bit? Not to compare too much to Nova, but they give you nice blue-highlited boxes for each that look tidy. These ones remind me of Sense, which is fine, but a little eh looking lol. One upside though is these activate much quicker than Nova's do and the animation goes right into the previews which is nice. Apex's animation into the previews are is a little rough/laggy though.
-Can you make the center dock app drawer icon long press normal like other launchers? Where we can still move it and eventually edit it when you implement that feature? Not sure why we need the settings menu when you long press on it, but I assume it's because not everyone uses a ROM that lets you add menu buttons (visible or invisible) to the softkeys bar at all times, which would let you access this same menu. Tough one here since for some it serves a purpose.
-When dragging an icon or widget to delete it from home screen, the "X Remove" option that you drag it to at the top is behind any Widgets or other things at the top. This may be because I use a 5x4 grid so maybe only custom sizes do this, but still.
-When we enable the app drawer icon vibration, can you make the vibration the lighter stock vibration? It's definitely stronger than the stock app drawer icon press. It's kind of nice but I kind of wish we had the option between the strengths. Possible?
-Looking at my Nova screenshot above (right one), can we have the Google search widget that looks like that? Which is the stock locked one, but we can add to only one screen? Not sure how Nova added it as a widget option, but it's not here in Apex, only the ugly gray one seen above on the left. In Nova, the widget is called "Quick Search Bar". If I knew how a launcher adds a widget option, I would pull it myself..
-Will you be adding a long press homescreen menu option similar to Nova's "Nova Actions"? In there, they have addable icon options for app drawer, show previews, toggle notif. bar, expand notification bar, default screen, voice search, nova settings. Maybe not that needed but an idea.
Thanks!!!
EDIT: Here is a screenshot of the missing previews that I keep getting. The bottom two screens are full of icons and widgets and sometimes other preview boxes are blank as well:
