I have just gotten the first stable release candidate for GSE2 out and up on Curse. (To get it via Curse Client you will need to set your release type to Beta.) https://wow.curseforge.com/projects/gse-gnome-sequencer-enhanced-advanced-macros/files/2366675
After updating your old macros are hidden. This is a bug that I am working on now. The important part was to get a working version out as fast as I could. To get to these macros, Go to Options and in the middle click Show All Macros
Then Go to Create Icon and Drag your macro to the action bar.
I am currently working on the Saving of these macros and not needing to show all macros to see them as we speak.
(There is too much broken with 1.5 and I wont be updating it.)
