I require to customize salesforce1 for my org with brand logo and colors. Please let me know how can I achieve this. Whether it is possible or not.
1) Salesforce Menu--> Mobile Administration --> Salesforce1 --> Branding.
Here, You can find the options to edit the brandlogo.
2) You can change the preferences/priority of the tabs/Custom Tabs displaying. If you don't need to use the "What I Follow" you can remove it.
Mobile Administration--> Mobile Navigation--> you can add/remove/move up/move down the tabs
3) Salesforce Menu--> Global Actions--> Publisher Layouts.
Here, you can align/add new/ remove the Quick action options. Thanks.
