Description h.i.m 2009-02-13 02:15:08 UTC
Version:           0.8 (using KDE 4.2.0)
Installed from:    Ubuntu Packages

In university, i have to learn and work with presentation-slides, which are converted to *.pdf files. 

When i have to search something, which is not text, but e.g. a picture of a Ribozyme or diagram, i have to go through all slides of a document to look it up.

Therefore i need preloaded slides. (and not just the very next one)
I want to go fluently and fast through all slides and not be forced to wait 2 seconds while every slide has to be loaded first.
My PC and Notebook store 4Gb Ram, a Quad (PC) and Dual Core CPU (NB), which are doing nothing until i zap through the slides(!)

I would recommend to make an extra check-box available (in aggressive mode), which allows Okular to preload the whole (or at least 20-30 slides of the) document. (maybe you can build in something like check if there is a minimum of 512MB of Ram left over)

This would make my work a lot of easier and faster ;)



Thanks in advance
