I have a few suggestions for improvement.
Sorry, it sounds like this user is asking for a different app than the one we have.
All of these requests are either 1) working as intended, 2) agreed to not be done, or 3) represented as existing tasks.
Include more fonts.
Android App currently offers Sans-serif & Serif options, these can be chosen in the "Theme" menu, found in Article Toolbar, or overflow menu (3 dots) in top right. We have another request to add opendyslexic as a font https://phabricator.wikimedia.org/T347291
Accent colour customization ability.
4 color options available in Theme menu, vetted to ensure they meet accessibility standards.
Fully functional scroll bar. (With customizable handle size and position)
There is a scroll bar within the Table of Contents.
Font colour customization ability.
Font colors are adjusted with Themes to ensure accessibility.
Scroll to top and bottom buttons.
The Table of Contents can be used in this way: Swipe to the Right to find the Table of Contents from anywhere in the page, or use the "Contents" option from the Toolbar or overflow menu (3 dots) in top right. Selecting the article title jumps to top of page, selecting About this Article jumps to bottom.
Include ‘Star’ and ‘Archive’ article features and also the ability to save to dedicated folders.
Reading lists can be used as folders: chose "Save" from the toolbar, Add to reading list, and Create a reading list. These lists of articles can be saved for offline use.
Increase toolbar capacity to six items.
Guidelines suggest limiting toolbars to 3 to 5 options. https://m3.material.io/components/navigation-bar/guidelines.
Ability to alter toolbar positions.
The team will take this feedback into consideration.
Hi @ARamadan-WMF, thanks for taking the time to report this! Please check https://www.mediawiki.org/wiki/How_to_report_a_bug and split this into separate tasks, to cover only one topic per task.
That allows to have specific task summaries which allows distinguishing when looking at a list of tasks on workboards, and it allows to track the progress and status of each request. Thus I am closing this current task as invalid. Thanks for your understanding.
