The new interface has appeared in all elements where work with files is available: CRM, Feed, Tasks, etc.
What has changed
The action icons have become bigger and each one is signed.
To add files, drag'n'drop them to the highlighted area.
In the settings, you can allow document editing, photo collage, or create new document.
You and your colleagues can create a photo collage in comments.
You can create docx, xlsx, and pptx files directly in your messages. When you close the editor, the file will automatically be attached to your message.
Each file you've added to the message has an action menu. It has the following options: insert into the text and delete. It also shows the file path.
