Attention: This script was written to be used with Tampermonkey (which is available for all major browsers). It does not work with Greasemonkey 4+ (a lot of scripts don't work on Greasemonkey anymore). It probably works with Violentmonkey, but I haven't tested that.
This script adds some functionality that I felt was missing from Manganelo/Manganato and Mangakakalot. It lets you go to the next chapter by pressing your right arrow key, and the previous chapter with the left arrow key. It also enables scrolling and navigation using the WASD keys. Additionally, it removes the space between the pages on series that you specify.
Webtoons tend to look bad on Manganelo/Manganato/Mangakakalot, because there is a small space between the pages, and sometimes it causes a gap in the middle of an image. However, actual manga and a lot of manhuas have well-defined pages, so I think they look better with the space present. Because of this, I wrote the script to only remove the space on titles that you specify. Here are before and after images in case I'm not explaining it well:

With the script:
If you want gaps to be removed from a particular manga, you have to add its title to the list in the configuration menu. I have already included a few titles with the script, but if yours isn't on there, you can add it easily. Just click on the Tampermonkey button on your browser toolbar, then click on 'Configure Titles' (this option will only show up when you're at Manganelo/Manganato/Mangakakalot), and a configuration box will pop up at the center of your screen. Then just add or remove whatever titles you want, and click 'Save'. Just make sure that you put each title on a new line, and make sure to spell the title exactly the way it shows on Manganelo/Manganato/Mangakakalot (including punctuation). If you don't want to have to type it, just click 'Add Current Title' to add the title of the manga you're currently viewing. Here are some images, just in case I lost you:
