The editor has “Grow Selection (Alt+E)” and “Shrink Selection (Alt+D)” functions. They will be much more effective in “Pattern Properties”, in the form of “Grow Pattern” and “Shrink Pattern” checkboxes.

I use these functions ONLY when importing patterns from old modules. I have to open Properties for EVERY single pattern:

• open Properties and change the size (64-128 row);
• open the pattern and select the necessary area (it does not take the whole pattern after enlargement);
• select the Grow or Shrink command.
  Sometimes it is necessary to process 20-30 patterns at a time in this way.
