CherryTree is above & beyond awesome! I wanted to start using an outline processor instead of a text editor to keep my notes, but CherryTree has greatly exceeded my expectations. Its capabilities go far beyond a simple outline processor allowing you to insert links in the node content that you are creating that link to another (internal) node in the CherryTree document that you are creating (so you are not limited to a strictly hierarchical structure: you can create an arbitrary network structure of your nodes), or you can link to a file or a folder on your system or to a website. It has node backwards and forwards navigation arrows that let you go to the last visited node in your document hierarchy (or network). It supports all kinds of formatting: font, color, style, etc. You can embed images, tables and code boxes (with syntax highlighting!) It can import at least 14 other file formats from other text/outline processors, as well as plain old text files and HTML files. It can export to PDF, HTML, textfile or to a new CherryTree document. Many more features, but it's also intuitive to use, so you can figure out most capabilities.
It's great, simple but all the features I need for keeping my lab book. Easy to search and possibilities to export to pdf or html.
best app for taking note. have realy rich text property. and easiy export your notes pdf format
