Hi 👋🏻

This is a more advanced suggestion, but I think it's a really nice idea: 🤔
You could add a search and replace tool, which can be found by clicking a button (maybe somewhere at the top of the gui).
This tool works similar to Strg+F. You could type in a keyword and it can show you where in the command (in all commandblocks) it's written. Then you could replace this string in one or all commandblocks.

For example you want to replace score1 in all commandblocks with score2 you could simply use this tool.

Did you understood what I meant? 😅
I know it's a really big suggestion, but it could be a nice thing to think of in the future.

Greetings, Ceddix 😄
