Entity Note: It doesn't make sense to handle attachments on Note::create. Attachments exist out of Notes, they are a thing on their own. Furthermore, they aren't always handled the same, they most definitely aren't always uploaded files. FileQuota: It doesn't make sense to check if a file is greater than max allowed upload size here. The plugin ensures a user is inside his allowed quota, it's ignorant to anything else. Whether a file respect max upload is a core thing that must be handled directly in the Posting component. TODO: The configuration regarding user and monthly quota must become FileQuotaPlugin settings and be removed from core. c90efe2c52 - [UI] Add mechanism for rendering note contents in different formats. Implement plaintext rendering. Use rendered field for note content, rather than the content itself
