Hi, first of all sorry if this issue has been already posted, discussed or suggested. I've made a fast search and I haven't found anything (
and I haven't spent much time, truth be said 
).
I've just moved from my old good PRS-650 to a brand new Kobo Aura HD and I really miss one handy feature available within Calibre and Sony devices.
In Calibre "Preference > Tweaks" there's
Specify renaming rules for SONY collections (ID: sony_collection_renaming_rules) which is pretty handy to get your books completely categorized in the Sony devices through collections.
As example I have this setting used in this way (just a summary, I've got more custom columns also used...):
Code:
sony_collection_renaming_rules = {'tags': 'Books by Tags', 'series': 'Books by Series'}
sony_collection_name_template = '{category:|>|.}{value}'
In this way I got a lot of collections in the device in this way:
>Books by Series.The Lord Of The Rings
>Books by Series.Discworld
>Books by Series.Belvilacqua
....
>Books by Tags.Romance
>Books by Tags.War.WWII
>Books by Tags.War.Spanish Civil War
>Books by Tags.Whatever
(And also >Books by Language, >Books by Original Language, and more).
This can seem a whole mess but using
PRS+ subcollections feature makes my Sony eReader content nearly as classified and categorized as inside Calibre. This PRS+ subcollections feature allows Collections with dots in their name being treated like subcollections, (in a similar way to hierarchical items inside Calibre). So if I want to browse books by Tags content it's pretty straightforward, and these Tags collections/shelves are not mixed with other collections/shelves derived from series, language or whatever.
But I cannot do the same procedure with my brand new Kobo.
So my requests would be:
- We need support for Subshelves (subcollections with the new name given in FW 2.10.0) >>> Request for Kobo.
- Then we need support in KoboTouch (or KoboTouchExtended) driver for that subcollections. I mean the Driver needs to translate the hierarchical items within Calibre into those new subshelves/subcollections in the device. >>> Request for davidfor and/or jgoguen.
- Lastly, it would be great if the both drivers used the Sony collections tweaks within Calibre. I mean, if I want to add the ">Books by whatever" prefix, I could currently build auxiliary custom columns, but the method available with the Tweaks is much neater and cleaner. >>> Another request for davidfor and/or jgoguen.
What do you think about all these suggestions?
(If "power users" find them feasible, I'd update my personal future firmware request thread).
