+### Tagging Profiles
+
+Select a set of tags and add/remove them from images without opening them. Just hover over image, click on tags and 
+you're done!
+
+![Tagging Profiles Showcase](.github/assets/profiles-showcase.png)
+
+### Custom Tag Groups
+
+Customize the list of tags with your own custom tag groups. Apply custom colors to different groups or even separate 
+them from each other with group titles.
+
+![Tag Groups Showcase](.github/assets/groups-showcase.png)
+
+### Fullscreen Viewer
+
+Open up the specific image or video in fullscreen mode by clicking 🔍 icon in the bottom left corner of the image. This 
+feature is opt-in and should be enabled in the settings first.

+# Extension Icon
+
+This folder contains original resources used to make an icon for the extension. Since I'm not really an icon designer, I
+ended up just composing the icon from sites logos + the shorthand name of the extension with fancy font. Nothing 
+special.
+
+## Sources
+
+All resources used for composing an icon are stored here as copies just to not lose anything. Original assets are 
+sourced from the following places:
+
+- [Derpibooru Logo](https://github.com/derpibooru/philomena/blob/40ffb1b75bd0d96db24fa7c84bce36fcb7f2935f/assets/static/favicon.svg)
+- [Furbooru Logo](https://github.com/furbooru/philomena/blob/cbfde406de34734403c06952bcaca51db6df1390/assets/static/favicon.svg)
+- [Tantabus Logo](https://github.com/tantabus-ai/philomena/blob/285a7666ae4be46ac4da36bbc9ac8fda9e5c0fc3/assets/static/favicon.svg)
+- [RoundFeather Font](https://drive.google.com/file/d/18ggNplAZNYtO4eNtMUpv3XpkeOAxSkxm/view?usp=sharing) 
+  - Made by [allorus162](https://bsky.app/profile/allorus162.bsky.social) 
+  - [Original Bluesky post](https://bsky.app/profile/allorus162.bsky.social/post/3mfqntff4j22i)
+
+## Rendering
+
+**Note:** You don't need to do anything to pack current version of icon to the extension. All icons are already pre-rendered and
+placed into the `static` directory. 
+
+For now, any change to the icons will require manual re-rendering of PNG versions of the logos used when packing 
+extension for the release. All you need is to open `/src/assets/icon/icon.svg` in software like Inskape, hide the 
+currently opened logo and toggle the required one and save it into `icon256.png`, `icon128.png`, `icon48.png` and 
+`icon16.png`.
+
+For the font on the bottom-right to work, you will need to install it from the file 
+`src/assets/icon/fonts/roundfeather-regular-1.001.ttf` (or you can download and install it from the source link).
+
+You should render them into `/static` directory in the following structure:
+
+- Place Furbooru icons into `/static` directory
+- Then add same icons for Derpibooru and Tantabus into `/static/icons/depribooru` and `/static/icons/tantabus` 
+  respectively.
+
+Resulting structure will look like this:
+
+```
+static/
+    icons/
+        derpibooru/
+            icon16.png
+            icon48.png
