Hi @Hidden_Collector That blue bar is a drag and drop indicator which is supposed to show up when you drag a tab out of one Orion window, and into another Orion window - it helps you to visualize the final location of the dropped tab.
This blue bar showing if you are not dragging is definitely a bug, but I wasn't able to reproduce it. Are there any reproducible series of steps that cause this to show? If so, I'd really appreciate if you could share some more details.
- Does the blue bar remain when you select the last tab?
- Does dragging dropping any tab in the same window have any effect on the blue bar?
- Does dragging dropping any tab from a different window have any effect on the blue bar?
- When you say it appears after using Orion for a while, is it when you bring Orion back from background, or it appears in an active window?
