When Quick view (
without plugins) is active and you browse through zip archives, TC search for determinate types of files like *.txt, read.me, etc. (in general plain text files) and the text appear in the quick view panel.
I miss this feature in a wdx plugin. It should be useful for big storages of zip archives like downloads, plugins directories of TC

, etc. for show this text in a custom column. In tooltips, in search functions, for move this information to descript.ion files or data stream, etc. The data could be shown like textline or xpdfsearch does.
Maybe a good start point could be the plugin
MIDlet developed by
byblo which extract information from a plain text in jar archives (zip archive renamed)
Just this, only an idea more.
