SmartOpenDir allows directories to be automatically opened with customised filer display options by matching any directory about to be opened against a set of wildcarded patterns and setting the filer display options immediately before displaying it. The latest version allows options to be changed for directories containing long filenames, useful because they look ugly with large icons. Note that if upgrading from 1.11 or earlier, you must edit your patterns files so that comments begin with the double-quote (") character instead of hashes (#). This is because it may be useful to have a # at the start of a pattern. Now compatible with RISC OS 4.
