PopClip-Extensions VS hammerspoon

Its menu appears appears when you double click text. You can download other people’s extensions &/or adapt them https://pilotmoon.com/popclip/extensions/

Popclip is a very popular application among macOS users that allows us to install small addons that are activated by selecting a text. It has plugins for the main search engines, but it is easy to create one personal for SearXNG. After downloading Popclip on the Mac we install PopMaker. Filling in the data is trivial.

It’s essentially a customizable pop up menu that appears near your cursor. Options range from copy/paste to translate. Here is a list of available extensions.

This doesn't replicate your exact request, but I use PopClip (https://pilotmoon.com/popclip) to handle a similar mouse-based copy/paste usecase, plus a number of others via extensions (https://pilotmoon.com/popclip/extensions). I recently switched upgraded my mac and it was one of the first things I installed.

Similar to PopClip on macOS. Like the contextual menu on iOS and Android but in this case, you can add extensions allowing you to do everything from the simple copy/paste to formatting text/list, send the text to OneNote, translation etc:

Another option for hacking something like this together could be HammerSpoon. I’ve spent some time with it, but haven’t tried integrating with Apple Notes, I mostly did stuff at the file system level to keep it easy.

For basic window tiling, I stumbled across Hammerspoon and the MiroWindowsManager spoon.

I use hammerspoon a lot and it seemed like scheduling SelfControl could be done using it so I created Hammer Control. Check it out!

Hammerspoon - Price: Free Desktop automation tool for macOS that allows you to write Lua scripts to control your Mac.

Assuming no one has a cut-and-dried solution that just works, would something like this be possible with say, AppleScript or another scripting tool like Hammerspoon? I've not used either of these tools before, but would be open to seeking out a scripting solution on my own if it's viable. Or am I going to run into insurmountable security restrictions?

Spark (not the email app). There are others like Hotkey and Hammerspoon.

I have tried different tools for this including Rectangle, but I've finally settled with hammerspoon. It solves the problem of window-management but you can also use it to create custom keyboard shortcuts and much more.
