Also, I think application should:

1. Configure the canvas size properly. Currently we have lot of unused space on the screen (see attached photo).
2. Display message like "[File is empty]" for empty files.
3. Correctly handle opening of a binary file (or with non-UTF8 encoding).

txt-files for the testing can be found here test-txts.zip.

about this part, we've a sort of toolbar at bottom area, meant to display some maybe minimal progress, some additional data. is evaluated inside draw method and yeh, if line don't fit, it won't be displayed, though it looks a bit worse than expected, maybe I wasn't that precise, would check

other 2 points, 2., I guess that won't be really hard, with binary 've to do more than those,
most binary files are about like lots of \0 symbols inside whose a bit fucked up by standard functions, so would require some preprocessing of it, maybe turning stuff into a hex view, which is, would be cool, but, I feel about it more like enhancement feature

anyways, thanks for feedback, would try to improve it :)

1. Why scrolling is enabled for case when whole file is already displayed on the screen? Checked with file 'latin.txt'.
2. Open file 'long_multiplelines.txt'. Press → (next page), then ← (previous page). Repeat this combo 5 times. Then try to repeat one more time and, instead of text, empty screen is displayed.
3. One additional thing – after each repetition of →← you will return to the other position in the file.

Most of the test files works perfect 🙂 But.
Open 'very_long_line.txt' and scroll (by ↓) to the end. Press ↓ one more time and then app freezes.

If user tries to open empty file ('empty.txt'), application crashes and Keira going to reboot.
