OMG yes! This is one of the things that makes the iOS app hard for me to use — I often end up unable to see the forest for the trees because small actions and sub-projects end up looking alike. So, another +1!
It isn’t actually the IOS app itself that is the problem, it’s the Ipad version of it. Action groups are much better handled on the Iphone. The solution on the Ipad doesn’t look finished. Here is a part of what I wrote to The Omni Group support in January 2016:
If you move tasks inside another task on the Ipad there is no way to see only that level of tasks. You can only see them indented on the level above, together with all other tasks on that level (much better solution on the Iphone, where action groups are presented the same way as projects).
Neither is there any way to avoid seeing actions in action groups when you are on the level above – to get a better overview –, as you can’t fold action groups the way you can with projects by tapping on the triangle to the left of the project name (much better solution on the Iphone, where the actions in action groups are automatically hidden when you are on the level above, as the Iphone only shows one level at a time).
As you can only show the level above actions in action groups on the Ipad, you can’t create new actions directly in action groups by tapping on the circled plus-button – the actions will be created on the level above. Then you have to open the action, tap on the button ”Move inside another item”, and choose the action group. And all this you have to do for every action you would like to put in the action group (unless there is some technique I’m not aware of)! (Far better solution on the Iphone, where you can create the first action, move it inside another action, and then – as the view changes to the action group level when you move the action there – create as many actions in that action group as you like simply by tapping the circled plus and then ”Save +” for the following actions – the actions will be created directly in the action group.)
I recommend all of you that would like to see a better Ipad solution to let The Omni Group support know that by e-mail to the address email@example.com, as they don’t count votes in the user forum.
