Screen / Page to find and merge duplicates

[CallumCarmicheal]

Describe your suggested feature

A dedicated page which would allow you to search for duplicates and merge them. This can be useful when restoring a backup prior to changing a extension like Lua Comic -> Lua Scans which I had over 50 manhwa. Using the Title, Alt Titles (if those are stored) and the Tracking to determine if its a duplicate might be a way to go about it.

This would be useful for restoring from old backup's which used different sources which may not be actively used anymore but you have already migrated some or all of the entries which are now duplicated.

Other details

Heres an example where this feature would be really useful:

I started using SyncYomi this month to sync read chapters between multiple devices and I started noticing I was missing some entries but assumed I accidently removed them after I had to change extensions for some websites due those not working. Today I realised it happens everytime I sync. I restored a backup from January and since then I had to migrate a ton of Manhwa from sources which changed like Lua Comic -> Lua Scans etc.

Knowing what entires I had already migrated would save a lot of time because the "Existing entry" shows the first entry which it finds not all of them, so if I had 2 or 3 of the same entries in my Library I am not able to differentiate between them.
