Using PhpStorm As Everyday & General Editor

Hello,

I intend to use PhpStorm replacing BBEdit/TextWrangler.

The most important issue I have right now is sometimes I quickly need to do CMD+N as a shortcut to open a new file, without being asked where to save it, what project or anything, Simply just opening a new document and ability to make note of something or paste a bunch of text.

I have read this post: https://intellij-support.jetbrains.com/hc/en-us/community/posts/206378669-Using-PhpStorm-as-default-system-editor-open-single-file?input_string=Using%20PhpStorm%20as%20General%20Editor

But my question remains unanswered, how can I do this on PhpStorm without any hassle? I just don't want to have the files in a project, but use all the wonderful features of this editor for single files, existing or new, and without being asked to specify a filename if a new file. Maybe I don't even want to save it, but I want it to stay open until I close it manually. Even closing PhpStorm & re-opening it should remember my previous session and reopen those unsaved new files.

How can this be done?

Thanks.
