I never access a server using a phone, tablet or try to edit a site that way, so I guess this all went over my head. Spruz likely will or has addressed the issue and I'll have to make a note to check this. The missing options are an iritation one really doesn't need.
Going to the site http://swifties.spruz.com/ on an Android tablet, the first thing I notice is that the public nav bar is not displayed in vertical mode. Turning to horizontal display, the public menu pops into view. In programming for a mobile device, one needs to keep this feature in mind. It's not usually an issue with desktop or laptop devices. I'll post to this as I go along, and find time to look at the issue.
Using an Android tablet with the default Android browser Chrome in horizontal mode, I attempt to edit this post. I notice that the editor immediately comes up with Source mode activated. In this mode only [source], [maximize] and [select all] buttons are active. The editor button panel itself is not to be found. As long as we are in this mode, the editor panel is not useful for most of the editor's functions.
This is the span element which contains the editor toolbar:
This is apparently not displayed in the mobile Spruz version page.
