BasKet is an open-source note manager for KDE. With its comfortable, familiar interface and freeform notes, it's captured a loyal base of fans. However, the app is only for Linux and requires KDE, which might be a bit heavy for some users. Many lighter weight options can be found with the portable filter and the list can be narrowed down with Markdown support and integrated-search.
