Labels > Homogenize Capital letters and Singular vs Plural

The labels are sometimes written with capital letters, sometimes not. Some labels are in plural, the others not.

I don't know which solution is better between:

• plural vs singular
• lowercase vs uppercase :
  • The words of a label take a capital letter
  • Words like "by", "of", "for", "a" in a sentence, don't take a capital letter (unless it's first word)

1/Modify "Add field" to "Add Field" and "Delete field" to "Delete Field"
2/ Button "Select Life Cycle" (see screenshot "Life Cycle")
3/I propose to rename "Add extra schemas to this document type" with "Extra Schemas" to homogeneize with the other toggleable titles , keeping same tooltip
4/Field type > "Floating point" should be "floating Point" (see screenshot)
5/ Tabs : Caps to "Edit Workspace", "Folderish Document Content" and "Section Content" (see screenshot "tabs")
6/ Creation Layout(same in view and edit layout): button "Select Resource" + "Before Layout", "Disable Local Layout" , "After Layouts"
7/ Advanced Search "Additional Query Filter", "Query Parameters", "Default Sort"
8/ Advanced Searc > REsults> "Maximum Number of Results by Page", "Maximum Number of Results", "Page Size Binding", "Use Global Page Size" etc;
9/ table Layouts "Add Selection Checkboxes" + "Additional Result Columns"
10/ Virtual Navigation "Additional Query Filter" + "Default Sort"
11/ Automation > Action enablement (+ style problems) see screenshot
Event Handlers
etc.
