Enhance Your App's Look: Font Size & Theme Switching

Hey there, fellow app enthusiasts! Ever wished you could tweak your app's appearance on the fly, without diving deep into settings menus? Well, you're in luck! This guide will walk you through implementing a super handy feature: quick access buttons for font size adjustments and theme switching. We're talking about adding those nifty little controls right in your app's sidebar, making it a breeze to customize your viewing experience. Let's dive in and see how we can make your app even more user-friendly and stylish.

The Power of Quick Access: Font Size and Theme Control

Imagine this: You're happily using your app, and suddenly, the text feels a bit too small for comfortable reading. Or maybe you're working late, and the bright interface is starting to strain your eyes. Wouldn't it be great to instantly adjust the font size or switch to a dark theme with just a click? That's the beauty of quick access buttons! By adding these controls to your app's sidebar, you're giving your users immediate control over their visual experience. It's all about empowering your users and making your app more adaptable to their needs. This simple addition can significantly improve user satisfaction and make your app stand out from the crowd. Think about it; a user-friendly app is a happy user, and a happy user is more likely to stick around. We're not just talking about aesthetics here; it's about accessibility and convenience. Catering to different visual preferences ensures that your app is inclusive and easy to use for everyone, regardless of their individual needs. So, let's roll up our sleeves and explore the how-to of implementing these fantastic features.

Now, let's break down the two main features we're adding: font size adjustment and theme switching. The font size controls will allow users to increase or decrease the text size with simple clicks. This is especially useful for users with visual impairments or those who simply prefer a larger or smaller font for readability. The theme switcher, on the other hand, will let users toggle between light and dark themes. This is not just a cosmetic change; it can significantly reduce eye strain in low-light environments and provide a more visually comfortable experience. Both of these features together create a customizable and user-friendly experience, making your app more enjoyable for a wider audience. We will use two different icon to represent the font adjustment features which are:

<i class="fa-solid fa-a"></i> with size modifiers 

And to represent the theme control we will use the following icons:

<i class="fa-solid fa-sun"></i> and <i class="fa-solid fa-moon"></i>

By incorporating these small changes, we're not just making your app look better; we're making it a pleasure to use.

Font Size Adjustment: Tailoring Readability

Adjusting the font size is crucial for ensuring your app is accessible and user-friendly. For users with visual impairments or those who simply prefer a larger font, being able to quickly increase the text size can make a world of difference. Similarly, for users who prefer a smaller font to fit more content on the screen, the ability to decrease the text size is equally important. By providing these controls, you're giving your users the power to tailor their reading experience to their individual preferences. This means happier users, and happier users tend to stick around.

Implementing this feature involves adding two buttons to the sidebar, one to increase the font size and one to decrease it. When a user clicks a button, the app should increase or decrease the font size, cycling through the available font sizes. If the user clicks the increase button and the maximum font size is already selected, the app should do nothing. Similarly, if the user clicks the decrease button and the minimum font size is already selected, the app should also do nothing. This prevents the font size from going beyond the acceptable range. The new font size should then be applied immediately and saved to the database, just as if it were changed through the settings dialog. To enhance the user experience, you might want to suppress the
