A selected subset of actions are presented as controls in the toolbar. The different sections in the toolbar can be dragged and positioned anywhere as small floating toolbars. Management of the toolbar is done by right-clicking on the toolbar and then manipulating the displayed menu.
In the main area of the application, several 3D views or plot windows can be open at the same time. One of them will be active and the active view can be either maximized to use the whole main area, or restored so that you can see the open windows.
Most of the settings and features of ResInsight is accessible through the **Project Tree** and the **Property Editor**. Selecting an item in the **Project Tree** activates the corresponding Window, and shows the item properties in the **Property Editor** available for editing.
Toggling a checkbox next to an item in the **Project Tree** will toggle visibility in the window. Toggling a checkbox for a collection of items will affect the visibility for all items in the collection. 
A *Case* in ResInsight means a Grid model with a particular set of results or property data. There are three different types of Eclipse cases and one type of Geomechanical cases.
This is a Case based on the results of an Eclipse simulation, read from a grid file together with static and restart data. Multiple Cases can be selected and read from a folder.
This Case type is based on a _`*.GRDECL`_ file, or a part of an Eclipse *Input* file. This Case type supports loading single ASCII files defining Eclipse Cell Properties, and also to export modified property sets to ASCII files.
This is a Case type that belongs to a *Grid Case Group* and makes statistical calculations based on the source cases in the Grid Case Group. See [ Grid Case Groups and Statistics ]({{ site.baseurl }}/docs/casegroupsandstatistics).
##### Summary Case 
This is the case type listed in the Plot Main Window, and represents an _`*.SMSPEC`_ file. These Cases are available for Summary Plotting. See [ Summary Plots ]({{ site.baseurl }}/docs/summaryplots).
There are only one type of geomechanical cases, namely the ABAQUS-odb case type. The geomechanical cases are sorted into its own folder in the project tree named **Geomechanical Models**  as opposed to the **Grid Models** folder where the Eclipse cases and **Grid Case Groups** resides.
A **Grid Case Group** is a group of Eclipse **Result Cases** with identical grids, but generally different active cells, initial values and results. These cases are called *Source Cases*. The purpose of a Grid Case group is to make it easy to calculate statistics across the source cases both for static and dynamic Eclipse Properties. See [ Grid Case Groups and Statistics ]({{ site.baseurl }}/docs/casegroupsandstatistics).
This file only contains *references* to the real data files, and does not in any way copy the data itself. Data files generated by ResInsight are also referenced from the Project File.
Statistics calculations, octave generated property sets, and SSI-hub imported well paths are saved to a folder named _`<ProjectFileName>_cache`_ in the same directory as the project file. If you need to move your project, make sure you move this folder along. If you do not, the calculations or well path import needs to be done again.
