1. Don't highlight/select address in hex view
2. Highlight hex strings
If i'm in Hex view, i can highligth hex values only by typing text representation in highlight field.
E.g. i have a text file with 'as' text:
00000000 61 73 as
If i type as in highlight field, both text and hex values will be highlighted, but if i type 61 73 - nothing will be highlighted.
3. Select Hex Strings.
Something like 'Copy as hex string' in main/context menu to copy
So in above mentioned case 61 73 would be copied (as a string but not raw bytes combination because it's not a hex editor).
