Hello,
2. The Find, Replace, Filter, Column (the second drop-down in the Filter toolbar) drop-down list widths can be adjusted by adding REG_DWORD registry values:
CWFind
CWReplace
CWFilter
CWColumn
at HKEY_CURRENT_USER\Software\EmSoft\EmEditor v3\Common
The default value is 200 (or 125 for Column).
I will think about adding an easier way to change the widths in future versions.
