only as an option ;)

this could also be done by changing colors, adding number relevance to tags (higher/lower most relevant), etc

But remember, there are users with laptops and only touch pads :)

Great idea!
But real benefit for users will be in grouping settings.

Ex:
editing will 'contain' all settings related for editing notes. Thus preventing this settings polluting other groups, like tags settings, visual, backup, time...

Ok, this is more than pleasant surprise :)
I thought it had to pass at least one month before somebody reply ;) You are really super fast!

To be more precise:
Regular edit uses tab for tabulation, up for moving cursor up, down for down, etc.
These are just common win settings for editing txt. Something people are used to.

If possible, just add check box for "regular txt editing".
Tab is just tab, down stops at eof - it doesn't jump to another input box...

But if you are willing to split those two, that's even better.
Check box for tab <-> ctrl+tab
Check box for regular up/down <-> cn up/down

Separating these two covers all options, but is harder to implement.
