Another plugin I made could also help: Editor Counter https://tid.li/tw5/plugins.html#%24%3A%2Fplugins%2Ftelmiger%2FEditorCounter
On the settings tab of the plugin you can activate an option to save every X characters. So whenever you have typed/added or removed X characters, an autosave is triggered. I use it at X=200 and feel rather comfortable with it.
Good luck!

Whether it is enabled or not, TW appears to constantly save whatever characters I typed to "Draft of <whatever tiddler>".
If I reload the page, the tiddler does not reflect the changes, but if I edit the tiddler, the "Draft of" does have the content.
If I cancel the edit, the changes are not persisted.
I was expecting auto-save to persist the edits to the non-draft tiddler.
Am I using it wrong?
