Increase whatever you call this. It makes it hard to drag tabs with the mouse. No wonder why Orion feels less… polished than Safari. You need to do an extremely thorough overview of every single little gimmick of Safari that makes it feel… perfect as a browser. Please do that sometime as I am running out of time sometimes…
As you can see in the first ideo, there is a mouse tab drag move hoer box that is invisible and has a much higher tholerance than that of Orion's, which amkes it much easier to move tabs around as you do not have to follow the otherwise very thing tab bar hover box to move your tabs. Secondly, there is a minor issue with how when you drag a tab out of itself, it does not concur the normal tab close animation and instead makes the tab at the end instantiate at faster than the velocity of light to the left, which should normally cause a planetary explosion, so please add an ease out animation at the end of that tab whenever I want to create a new window by dragging a tab out of the tab to create a new pocket dimension of tabs for more hyper-focused multitasking…
