Memo Software

I have found for a memo software instead of "紙" which can be used on linux since several days ago.
And I found two good softwares.

This is what is called wiki based on tiddly wiki( But this is intaractive due to utilizing javascript.
incidentally, a developer of "紙" develops this.

This is Emacs macro. This can be airily because this is a part of Emacs.
I selected this one.
