[13] Main View polish

ToDo

• improve text (title, preamble)
• make card size dynamic
• add some dummy images to the cards (some cards have an image, some not)
• add "time ago" to the card
• remove the arrows on the right side of the card
• padding should be equal on both sides (left, right), if possible
• optional add some nice own ideas

Acceptance criteria

• most oft the cards display the whole title (max. 4 rows) (not necessary for really long titles)
• the card size is dynamic, depends on the content
• some cards have images
• time ago is displayed on every card
