hecate's Issues

Diff mode

Some editors like dhex have a diff mode, which shows two or more files next to each other, scrolling in unison, and highlighting bytes that are different. This would be great to have in Hecate.

Hex Editing Features

Hi,

Can some basic hex editing features be added? E.g. find and replace etc.

Thanks in advance!

Hecate freezes

Hecate almost always freezes after a certain amount of use. I don't think this used to happen... might be some kind of channel communication deadlock. Any ideas, @kaos?

Pressing "Escape" in search field sometimes searches

Steps to reproduce:

Search for something
Press / to re-open search box
Press Escape to close search box

Expected behavior: Search box closes

Actual behavior: Search is executed using placeholder value

`panic: invalid interrupt` on WSL

I'm trying to run hecate on WSL Ubuntu 18.04.

I wget the .deb, then dpkg it. But when trying to run it, it gives panic: invalid interrupt
Seems to do this for any input file I try.

How to edit hex values (instead of the characters they represent)?

Really like how hecate is done. But I couldn't find out how to edit the content by hex value instead of by character?
