I like CDisplay in windows,
but when i use linux, i used comix and like it more than CDisplay.. you don't need to use different key to load the next zip files..
well, I like these kind of tools because:
1) no need to extract
2) can display 2 pages at once (i'm using a very high resolution display)
3) can zoom
4) easier to move around between files (can use mouse/keyboard shortcut)
2 things I like better from comix are:
a) it can handle multi level compressed file (some zip archives have zipped chapters inside!! this can be handled by comix and not CDisplay!)
b) use the same shortcut for "next page" and "next zip file".. so you can navigate between archive files seemlessly (no need shift+L)http://comix.sourceforge.net/
- not for weak hearted ppl coz the installation is a bit challanging.. (well i guess most linux users understand it though)..
