Recent improvements:

• Specify any plural words you want grouped with their singular e quivalent
• Much more responsive interface
• Increase available date range to allow older papers to be included
• Restrict the maximum size of high frequency words to avoid them dominating
• New fancy colour schemes
• You can specify certain words to remain uppercase (or mixed case) using the Repair uppercase option
• More robust search (should now work with the entire URL rather than requiring your ID)
• Use the transparency option to fade the colour for lower frequency words
