I am a daily user of Whats that Anime, website as well as app. I have searched thousands of anime through it, it has simply made my life comforting. But I would like to see a new feature in it, A Drag And Drop option, it will be helpful to many user as well as myself.
For web version consider this feature as just copy pasting the image.
Explanation - when we take screenshot from anime it will automatically copied to our clipboard. after that just for sec of searching we need to save it and again upload it for result. Instead of saving and uploading, it is really good if we can directly paste it into website after taking a screenshot.
For live demo check this out. You can either copy the image either by pressing key ctrl + C (for windows ) { or by right click to image and copy} or just take a screenshot as πͺwindows + shift + s and paste it by keys ctrl + V to this website
Take a look for reference about this feature.
Hope it will make scenes for web version.
When using the app on different devices or platforms like (web and android) it always have separate accounts for all those instances.
So we cannot access personal searches from these different instances in a single device. Hence a synchronized account would help to use all data from different devices into one instance.
Proposal
To have Google, GitHub, etc. sign in methods to synchronize all the devices/instances for a particular user.
