MasterRabbink Yeah, but I think that one was easier. We just have to see if they will implement this too. Good luck!
Add Last Update as Filter
DazzlingGem I expect this would as hard as the Legendary Novel Request Thread. Gwahahaha.
MasterRabbink Well, that one was bordering on the impossible (amost 700 posts now) so let's hope this one won't have to reach that far...
DazzlingGem Glup.

Yup, this is a good suggestion. Like one of the commenters above, I prefer binge reading, but sometimes I can't help myself and catch up on the incomplete novels I saved. I also save incomplete novels that I want to read in the future. I recently went through my library and found that two or three of the originals I was waiting to read (for originals I usually wait till its completed) were already dropped. It would have been nice to be able to filter that.
ace_cap Yes. This will allow easier way to find original novels. This is a step up for novel discovery.
Bump from another thread. Another readers want the completed thing.
