Well I did discover that there's a move counter hotkey but it's unlisted in the input options, I found it in the game files.
Just hold the ctrl key while mousing over a blank tile and it should tell you the moves and turns it takes to move the selected fleet to that particular tile.
Thank you for sharing this.
Grid/Icons: I really think that the zoom levels we can adjust at options are implemented in the wrong way - in the meaning of a bug. It would be so nice to define the point of appearence of icons and not the point of disappearence. Best would be to be able to define both (...) but if we can only define one then it would be much more useful to define the point of appearence.
I played with Old-Spiders mod (thank you). I like some icons at a closer zoom and others not. So I would define different zoom levels for ships & anomalies on one side and planets & relics on the other side (as example).
