Long time, no see!!
GridMove 1.18 is here!!
Ok, i did a small update. I think the problem with the highlight not appearing on top should be fixed now. I also added the "run" grid. It works in a similar way to the restore, maximize and ontop grids. Here's the syntax:
GridTop = Run
GridLeft = filename
GridBottom = name to be displayed
GridRight = working directory
"GridTop" must be Run
. GridLeft is the name of the file to be ran, GridBottom is the name to be displayed on the grid (like "restore", "maximize" and "ontop" currently do) and GridRight is the working directory (which can be ommited).
As for your doubt, here's the explanation.
When running an ahk script, a bunch of stuff is loaded. If it has hotkeys (like dialogmove and gridmove do), it loads one keyboard hook for each one. A mouse hook is also loaded. All this takes around 3-4mb per each script. So, joining them would spare you 3-4mb of ram. Now, if you don't have a 486 with 12mb of ram, this shouln't be a problem, and believe me: it'd be an almost impossible task, as ahk mostly uses global variables (actually, this is not ahk's fault, it's mine) and it isn't purelly multi-threaded.
Believe me, it surely isn't worth the trouble, and if you don't have loads of ahk scripts you woudn't notice the difference.
On the other hand, if it makes you feel better, you could join the small script you made with dialogmove, which is way simpler than gridmove. But don't think too much about it
