I am frustrated by the lack of a feature in Logos 4 that would improve bible study with the product. Whenever you float a tab and then redock it after using it, the resource doesn't necessarily return to the same panel it was floated from. This is problematic in maintaining the format of a layout. If any given pane should get down to only 1 tab, if this tab should ever be floated it will close the pane it came from when it is redocked thus destroying the layout format.
A floated tab needs to return to the pane it was floated from when redocked.
