Minor fix to keyboard so it can be dismissed without Saving a result

The app now stores your saved conversions persistently to your device, meaning that closing the app or restarting your device no longer leads to an empty list.

Resolves an issue with broken saves and settings screen safe areas and updates screenshots to be accurate.

Minor UI updates, some basic renaming and fixes to some UI bugs. 

Resolves some issues with saving Radius values.

Minor UI updates

*NEW*

1. Perfect››radius! Now you can easily work out the perfect inner or outer radius to accompany the radius of a shape you already know. Perfect for cards inside cards (otherwise known as Cardception)
2. Px ›› Rem and back again. Now you can easily just tap or swipe between Px ›› Rem and Rem ›› Px. No need to waste valuable tab space anymore

*UPDATED*

1. Updated UI with refreshed simplicity 
2. Better tab ordering
3. Better dark mode support. Colours are now more suited to the UI when dark

Px››Tailwind

You can now instantly convert pixels into Tailwind class values. This is perfect for when you've got design files created in pixels and you want to map out the relative Tailwind classes so it's built exactly as designed.

New widget! Some nice improvements to the widget UI to make it easier to read.

Fixes:

• Spacing and harmony is improved between title, result text and other elements
• Ems are now correctly referred to as Rems

** Version 3.0 Big update **

Px ›› Em is now Hand››over. In light of the new Line››height addition (more on this below) and some bigger changes that are planned, Px ›› Em is now Hand››over. Handing over from Design ›› Dev has never been easier.

• Feat: Introducing, Line››height. Simply provide the pixel size of your text, a ratio by which you want to space the lines and see in real time how this looks. You'll also get a print out of what pixel or em value you can use in your code to replicate the view on screen too.
• Feat: iPhone now uses the native TabView so you navigate the individual calculators via the bottom tab bar.
• Feat: Thanks to the new TabView, iPad now uses the iOS 14 Sidebar to allow you to switch between your different calculators.
• Fix: UI polish for the navigation buttons and some other tidying up and refactoring within the code for better performance.

This update is paving the way for the future of Hand››over. There's plans for other calculators to be included to make that Design ›› Dev handover experience better.

Feat: You can now insert one of the example scales directly from the Scale + icon. This adds the chosen value into the text field to immediately see the change in the conversion.

Fix: Small widget size was being truncated due to longer title. Fixed.

Fix: Missing title on Em ›› Px scales popup

New: Each result you save is now kept in the new save page (accessible by the top left icon). The Widget still respects the most recently saved result. You can swipe to delete on any of the saved items if you no longer need the result.
New: You can submit a feature request from the Settings menu
Fixes: Saving button simplified as it now has a dual purpose
Fixes: Some formatting and alignment issues

• Features redesigned Settings menu to: change app icon, see the example scales, see your recent conversion and learn about the App
• Some minor UI improvements to the Save toast

** NOTE **
You may have to delete the app and install fresh for the Widget to work

• Fixes an issue where you couldn't predict the timing of when a result was saved to the widget. Now, the widget timeline reloads as you save to ensure it's always up to date with your most recently saved value.
• Fixes an issue where the 'Em' label in the segmented controller could become truncated on larger screens (thanks to Simon Rice for catching this!)
• Includes new Toast-style indicator to demonstrate when your result is saved to the widget
