I'm a heavy user of my shell history. Frequent creation and destruction of different concurrent shell sessions clobbers the history quite well until there's nothing really usable left. This resulted in some inertia to keep windows around. zsh-histdb replaces the single-file ~/.zsh_history with an sqlite3-database - and this database is session aware. This way I can just have as many concurrent session as I want, and create / destroy shell sessions as much as I want and the shell history remains intact.
