Hello Layke1123 and welcome to Seven Forums.
For what you do, have you considered using some editor other than Notepad?
A popular recommended choice is Notepad++.
I prefer Crimson Editor.
These are free, and there may be other editors someone else could recommend.
Textpad is another editor I've used and like, but the last i know it's Shareware.
Put up with nag messages, or pay for the registered version.
These editors allow viewing/saving/editing multiple files in one Window.
You could have Thought1, Thought2, etc. files open in one Window at the same time, and easily switch between files.
I prefer Crimson because it has Print Preview.
Crimson is end of life (bummer), but it does work with Win 7.
Notepad++ does NOT have print preview that i know of (bummer), but it does have Rename.
You would have a bit of a learning curve, but it might well be worth it.
After you learn these editor(s) copying, editing, saving, viewing new/multiple files is easy, and a nice improvement over Notepad.
Below are some screen prints so you can see what I'm trying to explain.
Hope this helps,
