Looking for Airtable Interface Designer Toolbox

Hm, you can’t add any elements to that record picker section of the Record Review layout I’m afraid

As a workaround, perhaps you could create a Record Review layout for the Employees table?  That way you could display a rollup of all the overtime hours there instead

But can I add elements to the page in the interface in general?
Or is it just the preselected elements?

Airtable’s Interface builds are pretty constrained, but there are elements and components you can add…

So for your overtime hours example, you could add a number element or just a field that displays that information. In the building view, hover your mouse over the top of “Projekt auswahlen” and you should see a + sign and/or “+ Add Group”, which if you click will give you the options of adding more fields, a number, or a chart.

As for the fields if you click into the group there’s a side panel element “Data” where you can turn on and off fields from the data layer (and then you can move those around or edit them individually). It can be a bit tricky to click on exactly what you want to edit and the selection highlighting is pretty light.

Otherwise you can try using the Blank interface format, which gives you much more freedom in design, but is less compatible with public sharing.

Thank you very much ​@DisraeliGears01!

Unfortunately, there is no “+” when I hover over the top of projekt auswählen. 
I have the feeling that it is a permission issue, but I really don’t know where I can change this. I have the feeling that I checked everything, but maybe I missed something. In no permission setting (base, workspace, etc) I found the option “Builder”, only Admin, Collaborateur or Editor. 

Do you know where I might be able to change this?

Hmm, yeah this sounds like a permissions issue of some kind then. Since you’re talking about Admin permission levels, I’m presuming you’re on an enterprise tier plan? Sadly I’m just a Teams plan guy so I don’t have good first hand knowledge of the Enterprise level administrative tools.

Aside from the places it’s seems like you’ve looked (inside Workspace settings, in the base share settings), have you gone into the Builder’s Hub area and looked in there? I believe that’s where the Enterprise level admin controls live. To access the builder’s hub, click your profile icon in Airtable and it should be fairly far down the dropdown list, just above Trash and Log Out.
