What are tags for?
Tags give your notes context and meaning. The main advantage of tags is the fact there can be many of them for a note (unlike a folder) and it's easier to categorize them that way. For instance, a note titled "Recipe of a vegetable salad". You can put it in the Food folder, but you can also add tags - vegetables, salad, tomatoes, cucumbers etc.
How to add a new tag to a note?
Press on Add tag on the tag panel.
Start typing your tag's name. If you already entered tags before, you will be prompted with any matching ones. You can confirm a new tag by pressing Enter. You can exit the create/edit note mode using the ESC button or through a mouse click in the editor.
How to delete a tag from a note?
Press on the X next to the tag name.
How to rename a tag?
Right-click on the tag and press Rename.
