First of all, thank you for creating TF and keep it the awesome tool that is is (I couldn't work without it as it tremendously helps me with my productivity).
As a long-time user (now on MacOS 10.12.3 and TF 1.9.3 on a late 2013 27" iMac), I've noticed the "Go to folder" feature (invoked by shift+cmd+G) seems to have stopped working properly quite some time ago when two tabs are in side-by-side mode.
Regardless of where the focus is (i.e. in the left or right tab), the pop-down window always comes up on the right-hand side. Consequently, the folder I am going to is always shown in the right tab. This behaviour impedes with my workflow and is quite annoying. Is this meant to be as it is or actually a bug?
That windows also slides so far down that it becomes detached from the tab's column title bar. Not sure if this is intended either, since the window has still got that typical "drop shadow" at its top which makes no sense when "free floating" - yeah I'm nit-picky here .
