This version fixes a bug that doesn't allow certain servers under 1.15 to run the plugin. Due to 1.15 adding new sign types, it wont work with any version less than 1.15, so I separated them into two separate .jar files. Both can be found in the downloaded .zip.
I've also added floors to the signs (toggle in config). Add a number to the third line of the sign, and it will take you that many spots up or down!
That's about all for now, thanks everyone for using my plugin!
