Repositioning file tabs - How to get it to work better (more like Dreamweaver 8) ?

[Due to a server upgrade, I was recently forced to switch from Macromedia Dreamweaver 8 to Adobe Dreamweaver 21.5.  I've encountered several issues with Dreamweaver 21.5.  This is one of them.]

In Dreamweaver 8, you can reposition tabs by dragging them left or right.  

In Dreamweaver 21.5, when I drag tabs left/right, I must be releasing them too high or something, because they often end up opening a new coding window/pane, which is really annoying.  I then have to carefiully drag the new window's tab back down to the original window's tab list.  This takes time.  Time which I could have spend coding.

Is there a way to prevent Dreamweaver 21.5 from opening multiple coding windows, specifically when repositioning tabs?

Also, while on the subject of tabs, Dreamweaver 8 lets you scroll through all the tabs horizontally.  Dreamweaver 21.5 instead has a double-arrow thing on the right which lets you select tabs from a drop-down.  While this lets you find tabs quickly, it doesn't let you quickly reposition tabs to the beginning of the list.

Let's say you have 40 tabs open.  What's the easiest way to move a tab from the 40th position (far right) to the 1st position (far left)?

Thanks!
