It would be really nice if I could examine a file that I've saved while still running WS. Would it be possible to have a different program that simply reads the WS file as it does now so a person can collect packets at the same time as WS is collecting packets so someone can analyze a saved file using the separate reader software. Since it doesn't have to collect and store it shouldn't be that complex.

It would also be nice if there was a pdf manual that I could print out too. I know this stuff changes but there was an article in Scientific American several years ago about research showing that people have a much higher retention rate when reading something off paper verses a screen. A manual for v 2.6 of WS would be great too.

On a different note applause for all the people that developed this for Macs. It uses less than 1% of the CPU and that is MAGNIFICENT! Good job!

Thank you,

Paul

You can - just open multiple Wireshark windows. If you are on a Mac, you can try something like this:

open -n /Applications/Wireshark.app

From: https://osqa-ask.wireshark.org/questions/50713/how-to-open-multiple-wireshark-instances-in-mac-os-x

A manual for v 2.6 of WS would be great too.

Wireshark is on 3.2.7 so you will find it difficult to find people who are going to work on such an old version.

open -n /Applications/Wireshark.app

Ideally, that wouldn't be necessary, but, to avoid the need for -n, Wireshark would have to be modified to allow one process to have multiple captures open in order to make it function more like a normal Mac application. Wireshark currently maintains all the per-capture state as global data; it would either have to maintain most if not alll of it as per-file data, or would have to split the UI and dissection into separate programs and have a single UI process communicate with multiple dissection processes, one per file (that's how Safari and Chrome work; it may have some safety advantages, which I think is one reason why those browsers do that), or would have to do something else to resolve that.
