Thanks for your contribution, @shikuz!
Unfortunately, I'm struggling to use the plugin - I'm always getting a red message "Please select a note first".
- I have a note selected, active. It has a
time-slip tag
- I add a "Task name", as well as a "Project name" and click "Start"
- The error message appears
- The task name and project name I entered are cleared

I do have a lot of plugins installed, many are inactive - please see below for plugin list, versions - however my Joplin is generally quite stable. I'm using the Detailed note list style, I tried with Compact as well.
The screenshot below shows I have a note, with the time-slip tag.
Your help would be much appreciated. Hopefully I'm just missing something obvious, but also, I hope it's not too obvious!
