Tags organise your entries, such as “Work” or “Shops”. An entry may carry no tag, one or several. You assign them in the entry under Tag: the field searches existing tags, and + creates a new one.
The Tags page in the bar shows every tag with its count. Tapping one shows its entries; the menu on a tile renames or removes a tag.
The search field sits at the bottom, above the bar. Chips show where the term was found: per field (title, username, address …) and per tag, each with a count. The number on a chip is exactly what a tap on it leaves.
