You can use this website actually called mangaupdates.com to keep track of manga that you’ve added to your list, or if you have an iOS/Android device you can download this app called Manga Rock (free for lite version) and basically they’ll tell you how many new chapters have been released for any manga that you add to your “favorites” list.
I personally don’t use either of these since I just read manga whenever I feel like it and not immediately when it’s released.
Hope this helps~
Thank you! Well, I used Topaz Clean & Denoise + screentones from this guy to go over any blurred/ugly patterns from the scan. Don’t know if you wanted a detailed tutorial but hope this helps!
