Ideas to simplify and speed up user interaction with Table Of Contents:
Indicate in TOC which layers are edited and which are not (grayed out) while editing.
Indicate which layers are labeled, which failed to draw or have overlapping labels.
Match layer properties – simple one-click tool to copy all or selected properties (symbology, definition query, labels) between layers or dataframes (Format Painter in Office Word, AutoCAD Match Properties).
Match layer symbols simply by drag & drop between symbols from different or same layer in TOC (entire symbol, only fill or outline).
Organize layer symbology with mouse directly in TOC – manipulate symbol legend items easily without the need to run layer properties dialog box (create, move, delete, group/ungroup categories, headings, organize quantities).
Paste Layer or Add Data to exact location in TOC (one-step procedure).
Select layers with rectangular marquee in TOC (like Windows Explorer).
Common source folder replacement in TOC List By Source mode – simple and direct change of one or more base source folders or databases by rename or browse.
