When modelling microflows often you have to insert new items between existing items. When you do this by right-clicking on a connector and choosing insert, it already moves all the items to the right of the item further to the right. There are a lot of other scenarios however, where it would also be handy to make space easily. For example when you want to paste existing actions in between an existing flow, or when you want to add microflow actions after the last action in a loop, when you want to make some vertical space between two horizontal flows or when you want to remove unneccessary white space.
When holding ALT, you can click and drag all items to the right of your pointer to the right or left.
When holding ALT, you can click and drag all items below your pointer down or up.
This way it is way easier to create some additional space to add new models. And it becomes a little less cumbersome to make easy to read microflows.
See example below:
After holding alt, clicking at the red dot and dragging to the right:
After clicking the red dot and dragging down:
And the same can be used to remove the empty space
