When creating a new entry or when editing the entry type of an existing entry in a library, it would be useful, if tooltips describe each possible entry type.

The required content of the tooltips could be simply used from the following files:

• entry types in biblatex: http://mirror.easyname.at/ctan/macros/latex/contrib/biblatex/doc/biblatex.pdf (p. 8ff, 2.1 Entry Types)
• entry types in bibtex: http://mirror.kumi.systems/ctan/biblio/bibtex/base/btxdoc.pdf (p. 7ff, 3.1 Entry Types)

Requirements:

• A tooltip should contain detailed information for what this entry type is used.
• The information within a tooltip should be self-contained, without the need to look up other external documents and without being linked to other entry types.

The tooltips could be added in the following areas:

• When the "Select entry type" dialog is opened (e.g. Library > New entry)
  • Hovering a button of an entry type should show the tooltip
• When changing the entry type in the entry editor. (left side of the entry editor)
  • Hovering an entry type in the list should show the tooltip
• When right clicking a reference in the main table and clicking Change entry type
  • Hovering an entry type in the list should show the tooltip
