Changelog v4.00
First of all, let me to apologize with you: this v4.00 was ready since the introduction of the validation score in the online repository (this means since the end of October ^^') but unfortunately for several reasons and omissions on my part it has remained in oblivion until today. In the last months, then, I noticed again a significant increasement of the interest for custom themes (certainly due to the release of h-encore) in the online repository and so I remembered that there still was this v4.00 to be released and, well, what better time to release it if not now? And so here we are

Because it's been a long time since when I introduced the various changes, there may be something else I do not remember now, so please consider the following list just as a “summary” indication of the major new features in this v4.00 and have fun exploring the app to discover the other minor new features:
- Now after a (successfull) installation of a custom theme the application will return to the repository menu (and not to the main menu like in the previous version).
- Added a check at startup that will warn the user if the henkaku safe mode is enabled.
- Fixed a bug in the function to check for the available space before to extract the custom themes ZIP files.
- Changed the preview screen of the uninstallation menu, now the size value will appear together with custom theme's data (and not under the preview images like in the previous version).
- Changed and shortened the message in the cache menu screen.
- Added a new function to dump the current official theme in a folder (so as you can use it just as a normal custom theme in the future).
- Added a new function to set the partition to use for installations.
- Rewritten the general code to support other partitions besides ux0 (specifically ur0 and uma0).
- Added a function to save (and load at startup) the user's choices for partition to use and BGM playing status.
- Any opened footer (with commands list) will be closed automatically when the user returns to the main menu.
- Added a new function to check for new versions of the custom themes in the online repository.
- Added a new function to look for a match between the installed custom themes and those ones in the online repository (useful to check for any new version available for it).
- Added a new sort choice (by validation score) in the repository menu.
- Added the validation score inside the custom theme's data in the preview screen in the repository menu.
- Added a command to open the web browser to view the detailed validation report for any custom theme in the repository menu.
- Added a new function in the main menu that will open the theme settings, so that the user can now apply a theme directly from the app (without the need to go into the PSVita Settings menu manually).
- Fixed a bug with the view of the version value of the custom theme in the uninstallation menu.
- Added a new command to jump to a specific page in the repository menu.
- Now if the upgrade function of the app can not find Molecularshell installed then it will use Vitashell instead.
- Fixed a bug that did not allow to uninstall any custom theme with an apostrophe in its title.
- Added the possibility to import the preview images from the ux0:ctm folder instead to download them from the internet.
- Now if the application can not download the image previews then it will show a placeholder image at their place: thanks to this fix you'll can browse and download custom themes from the online repository even when imgur has issues.
