Juggling systems is goofy but as long as they're web based it's easy, go old school +customer data folder ++customer name > links to trello,slack go here +++project name > links to trello etc. go here then I have a todo.md or todo.txt using imdone-atom with snippits, gives you a text based kanban, you can open project folders with atom --add c:\customers\abc\project1 and alt-t for tasks also alt-j is journal where you can try to kanban all customers if you're ocd documentation should not go in a ticket system, it should go in a wiki my fav is a combo of integrated apps like trello/slack, jira/confluence, github/gitter tasks are todo/doing/done and done includes closing their ticket system and updating their wiki or whatever they're using like a wiki
