.jar files under XFCE, especially for Chromebooks

Good Evening, I recently purchased some wonderful software from Inkwell Ideas and came across a little hiccup. Under XFCE, for some reason, I cannot use the GUI window to flag my .jar as an executable.

It's not a huge deal, but some versions of Linux simply have a checkbox. I like easy. The "hard way" of opening or running a .jar file is to open the terminal and type:

java -jar filename.jar

Not so hard, I guess. But what if I simply want to double click that .jar file and have it open for me? The command is:

chmod +x filename.jar  

Reading the command makes me chuckle. "put the x in the box" is the command. Why not an easy little box. This is handy terminal usage information for all .jar files from Minecraft to Hexographer. One note on HexOgrapher is don't forget the little "o" between x and g. For whatever reason, I say "Hexgrapher" and then want to type it that way. It does not work, don't bother doing that.

I can't wait to review this software. It looks amazing. If you are wondering how you came to be here from MeWe, I am the author at These Old Games. The Unpwnd website is my tech site, which is not typically useful to RPG and OSR gamers. Not much can go wrong with pen and paper, so I like to keep them separated.
