What it does

• Hover over any word: a pop-up shows how often it is used and every line where it appears, with a few lines of context.
• Spot unused items quickly: a word that appears only once gets a red-orange header. A variable that is declared and never used stands out immediately.
• Comments don’t count: a variable that is only mentioned in a comment still shows up as unused.
• Strings are counted separately: a variable that is only used in dynamic SQL is not reported as dead, e.g. @CutoffDate inside EXEC sp_executesql.
• Click to keep and jump: click the word to keep the pop-up open, then click a line to jump to it.
• Your colors: the SQL is shown in the colors of your SQLinForm profile. Light and dark themes are both supported.
• Everything is included: it reads the whole script, also parts the Navigator tree doesn’t show, such as DECLARE.

Like the Navigator, it needs no database connection and works with every dialect the formatter supports. It just counts words and does not parse or execute anything, so please treat the result as a hint, not a proof: SET @x = 1 counts as a use, for example.

You can open it with the new magnifier button in the toolbar, or with the Usage Inspector tab next to Formatter and Navigator.

As before, I appreciate any suggestion or error feedback :-)
