Main Toolbar
The toolbar runs across the top of the main window and gives one-click access to Aquila's most common commands: managing workspace files, creating studies, and opening the editors. The buttons are grouped as described below.

Workspace Buttons
The toolbar begins with buttons for managing workspace files.
| Button | Description | Details |
|---|---|---|
| New | Create a new workspace (Ctrl/Cmd+N). | New Workspace |
| Open | Open an existing .aquila workspace (Ctrl/Cmd+O). | Open Workspace |
| Save | Save the current workspace (Ctrl/Cmd+S). | Save Workspace |
Study-Group Dropdown Buttons
Ten dropdown buttons group the study types by phenomenon. Each button opens a flyout of related study types. To create a study, click a dropdown button, then click a study type in the flyout. Every study type is also available from the menu bar.
| Dropdown Button | Study Types |
|---|---|
| Aspect Studies | Mundane Aspects, Aspect Hotspots, Lunar Phases, Transiting Aspects, Aspect Activations, Conjunction Activations |
| Aspect Patterns | Grand Trines, Grand Trine Activations, Stelliums, Stellium Activations, T-Squares, T-Square Activations, Yods, Yod Activations |
| Parallel Studies | Mundane Parallels, Transiting Parallels, Parallel Activations |
| Station Studies | Mundane Stations, Retrograde Cycles, Station Hotspots, Station Activations |
| Planetary Cycle Studies | Inferior Planetary Cycles, Superior Planetary Cycles |
| Ingress Studies | Hotspot Transits, Sign Ingresses, House Ingresses |
| Declination Studies | Nodal Transits, Solar Limit Transits, Heliacal Phenomenon, Latitude Extrema |
| Arc Studies | Speed Extrema, Maximum Elongations, Mundane Arcs |
| Solar Eclipse Studies | Solar Eclipses, Solar Eclipse Hotspots, Solar Eclipse Activations |
| Lunar Eclipse Studies | Lunar Eclipses, Lunar Eclipse Hotspots, Lunar Eclipse Activations |

The Declination Studies dropdown lists its study types in a different order than the menu bar does (the toolbar places Latitude Extrema last, while the menu bar places it second). Both reflect the application, and every study type is available from both.
