I'm making the decision to split Zenith Grabber into Regular and PRO versions.
Zenith Grabber is a free program--running it does cost me money, so if you like what I do and want to support me then this is my way of saying thank you! The features you gain are mainly just quality-of-life and not something everyone would need.

The reason for this is that development can be very time-consuming, and the automatic updates feature has required me to burn money every single month since its release. Being completely free just isn't sustainable anymore.
Buy it if you would like to support me, that is all!

I will never make a major feature a PRO requirement.

The PRO-exclusive features are:

• Automatic Updates: Instead of returning to Itch.io and manually downloading and extracting everything, you can simply press a button in the app and have everything downloaded and installed automatically.
• Mod Support: If you want to add your own support for a website that isn't in Zenith Grabber already, you can! All you need to know is the very basics of the Lua programming language, which is one of the easiest languages in the world.
• Advanced Sorting: You can sort your search by most-liked instead of by most recent. Not all websites use the same sorting tags, this option will automatically handle it for you and supply the correct one to each website.
• Source Finder: When viewing a post, you can click a button to be taken to its original source (Twitter, Pixiv, etc).
• Customizable UI: You can change the colour of the entire UI from red to whatever you'd like.

Side Note:
The old automatic updater will no longer work; PRO will need to be purchased in order to continue receiving automatic updates.
