Few advised enhancement

[ToUpgrade]

Hi there if you are still there proceed with this module? I still have some needs after applying your module， sensing that we may share emic needs, and the possibility you may fulfill the needs.

1. about changing the level of heading: based on your implementation of directly changing to a specific level, can I just increase or decrease the level by pressing alt + '+' or any shortcut.
2. about adjusting the nested structure of headings with its paragraphs jointed. I always in a case when I plan the headings in the first place but later to be found needed a change of the nested structure.

have you ever run into cases like this or do you sense kind of cases is common around then please note me if you feel any intent.

Hey! I try to support the plugin, but I have somewhat limited capabilities due to the fact that I am a very far from programming person :)

As for the shortcut to change the heading level - such an idea was, in principle, it is not difficult to do, it just adds a couple more keyboard shortcuts to remember (while we often already know which heading level we need).

But along with changing the heading level for a whole block of text, to edit the nesting of sections when refactoring the text - looks interesting, thanks. I'll try to do it
