The last time i’ve heard is that tomboy is related to LGBT community term but that was changed when I’ve encountered a semi-post it notes desktop application in Linux Desktop. Yes its a software , a note taking software that helps a lot in organizing and documenting text. I’ve used this one for quite some time. Googling for some related documents on this software, i’ve found out that its not limited to Linux OS alone, but for Mac and Windows as well.
It has a wiki link system that when you write something and decides that there will be another link on it, you just have to click the link button.
If you’re in debian based distro, just do “apt-get install tomboy” , should be automatically added in your system.
