Currently, the audit log of a server has two filter options: by user, and by action. However, only one user and one action can be selected at a time. A great addition to the filters would be the ability to multi-select and/or multi-exclude options.
For example: a server has a bot-mod that automatically grants roles to users. Adding filter options like this would allow for excluding actions performed by that bot, and make it easier to focus on human actions without having to go user-by-user or action type by action type.
