Hi @Maria_Korolov… I’m just getting started with Coda (a few months ago) and coming from 25+ years as a Sys Admin, DBA, and programmer, the first thing I did was go looking for how to create/manage global vars and blocks.
Finding that it’s not native to Coda, I created the following structures for Global Blocks, Variables, and Button Labels in our internal Docs/Systems.
You can create a 1 row table with buttons and then create views of that table to display the same buttons on other pages. You can also hide gridlines for the table and have it appear just as a canvas button.
