"Delete chapter after read" toggle for each title

[Raidou13]

Why/User Benefit/User Problem

Most nof the time i delete download chapters of what I already read but I don't want to toggle the "Delete chapter after read" because Sometimes i want to keep the downloaded chapters of certain series, but it's a pain to delete it manually right after deleting it, so Can neko have, the "delete chapter after read" be set per Series rather than globally?

Similarly like if you want to set the default reader to be vertical or horizontal for each series.

What/Requirements

Can be set from the title page or on the reader .
