I just got my first Kobo e-reader a few days ago and I have been trying reading ePubs and PDFs on Nickel, KOReader and Plato. I have to say, out of the three, I like Plato a lot, especially when it comes to PDFs! The UI controls are very intuitive and highlight response is just so smooth and speedy! Thanks a lot for making this
I have a few questions that I cannot figure out for now and would appreciate some generous guidance:
1. Is there an option to save the highlights and annotations/notes to the PDFs and ePub files?
2. Is there a way I can see all my highlights and notes/annotations of a particular file?
3. How can I extract my highlights and notes/annotations?
It seems like what I make on files on Plato stays inside Plato and are only viewable when I read the files on Plato…
Some novice feedback that I could provide:
1. I really miss the feature on Nickel that I can slide on the left side to adjust the backlight brightness. The L shape gesture at the bottom left corner for jumping between saved profiles or toggling it on/off could be a workaround but still not as handy as the direct real-time adjustment.
2. The current annotation/note field is limited to one single line, which can be hard to read and adjust when you write longer texts. I also hesitated a bit if I had to hit ‘Return’ on the keyboard or just press anywhere outside the pop-up to save the note; wondered if my note would be saved or discarded.
3. For some reason when I type capital letters and/or punctuations in note/annotation, Plato starts to slow down its response. The delay becomes increasingly apparent even after this annotation/note window has been closed. It eventually froze my Kobo (Libra H2O running Plato 0.9.6) as I continue my reading, highlights and annotation. I had to reboot thrice for reading and noting sparingly a PDF of just 19 pages. :-/
4. I kept digging around for a Setting page at the beginning for customisation and realised there is not really one.

Which is fine since all the available options are actually in the menu/navigation most of the time. I was just expecting to have some settings, e.g. on lock screen display.
Once again thank you for making Plato! I hope it will grow more powerful over time.
