I have quite a few large template nodes in my project that i sometimes work on. When debugging the results i have to click ok and then deploy to see the changes. After this i have to re-open the edit panel for the template node and then scroll to where i was working. What i miss is a 'apply' butt…

I've always liked the fact that for function nodes, markdown , template etc. , after you make your change and deploy, and you open the node again, ite remembers what line you were editing. Ok. I do lose undo while in the node, but outside of it undo still works.

“You appear to be the only person wanting this” is perhaps a bit of a misunderstanding. This forum thread has been open since September 2019, but I don't see anybody else agreeing this is a problem, I think that speaks for it's self.

Losing undo history Just to be explicit - this is undo history within the edit dialog (ie the monaco text editor) - not Node-RED's broader undo history that treats a single close of the editor dialog as a single undoable event.

Programmers often focus on how difficult a problem is to fix, while users care about the fact that they still have to deal with it every day. Many users may not realize how much small improvements like this can simplify their workflow. In most other applications, you can simply press Ctrl+S. In Nod…

[image] knolleary: ndo history that treats a single close of the editor dialog as a single undoable event. Yes. And that is also a point to make. if i make some changes and deploy without closing the editor. I'm still able to undo my change in monaco, redeploy, and i'm back to the way it was…

I'm not saying it will work out but could a chat with AI come up with something? Like I did when AI created the tab manager. I spent some time in a conversation with Google AI, asked the questions and it came up with a fully working plugin. Since the core of Node-RED is open I'm sure AI already know…

The monaco editor state can (undo history) can be saved and restored // Save state before switching away or disposing const model = editorInstance.getModel(); const viewState = editorInstance.saveViewState(); // Later, when restoring or recreating the editor editorInstance.setModel(model); editorI…

If done, should probably be on a timer so that editing many nodes doesn't cause too many overheads.

In that case, it might be possible to "cheat" and do the "done → deploy → reopen + restore state" dance if the Deploy button is pressed while an edit panel is open. I keep forgetting that the Monaco editor isn't just another input element :face_with_tongue: I was going to say that we only need to …

Well I remember asking about this, and whether it could be included in the Node-red v3 release.

So it seems that far from @svefro being alone wanting this, lots of people have requested it, over several years.

For sure that does not mean the team should be devoting time to providing it.
