Hello,

it would be nice if there was a way (a button or key combination) to hide PDF viewer without having to go into the settings.
For saving space I often use the HTML tags <details> and <summary> like below:

Welcome to Joplin! :spiral_notepad:

Joplin is a free, open source note taking and to-do application, which helps you write and organise your notes, and synchronise them between your devices. The notes are searchable, can be copied, tagged and modified either from the applications directly or from your own text editor. The notes are in Markdown format. Joplin is available as a :computer: desktop, :iphone: mobile and :abcd: terminal application.

Maybe this could be a nice solution?
