-Ability to click on the blue attachment icon directly instead of having to select the node, then choose the type of attachment you want to view on the menu
I shall implement it soon.
- For link attachments, a label field since some links are pretty meaningless when it's just the web address
You mean a separate field in inspector panel for each node to store its own urls? You could store the url directly into the node.
- Ability to undo deleted nodes
It is currently implemented. After deleting a node, click on Edit->Undo to undo it.
- Multi-line support for node labels
It is implemented as well. As mentioned in help, press 'shift+enter' to put a line break.
- Ability to reorganize nodes
I can add the ability to create a new parent node. Assigning different parent, I will check into it.
- Option for document to automatically save
This is also implemented if you choose localstorage for saving. What I recommend is to choose this storage option when you start with a map and eventually storing the final map into another storage.
