select two files to compare

[corobin]

feature request: it would be awesome if there is a mode where you could select two files to compare

current behaviour:

1. select one file via from > file
2. select action > generate
3. copy+paste the generated hash into custom hash field
4. from > file to select second file
5. action > generate
6. action > compare

this is a pretty clunky multi step process

proposed feature:

1. select one file
2. select another file
3. Press a button

expected behaviour: the app hashes both selected files and shows their hash and comparison result on screen
