Performance Tips

​
Reduce Input Delay

If the toolbar appears too slowly:
  • Lower the InputTime setting to 200ms or 250ms
  • Note: Very low values (less than 150ms) may cause accidental activations

​
Optimize for Specific Language

Instead of using “ALL” languages:
  • Select only the language(s) you actively use
  • Reduces visual clutter in the toolbar
  • Faster character selection with fewer options

​
Enable Usage Frequency Sorting

If you frequently use the same accents:
  • Enable SortByUsageFrequency
  • Your most-used characters will appear first automatically
  • Reduces navigation time
