If you want to try to cut down on clicks on CRM forms, one thing you can do is create a ISV button for actions they perform a lot.  For example if users create  appointments from the contact form, they would have to either go to Actions > Add Activity >Appointment in the top menu  or click on Activities > New Activity > Appointment from the menu on the left. 

Here is the shortcut.

Add a ISV button in the isv.config.xml file.

<Entity name="contact">
<ToolBar ValidForCreate="0" ValidForUpdate="1">
<Button Title="New Appointment" ToolTip="Create a new appointment." Icon="/_imgs/ico_16_4201.gif" JavaScript="locAddActTo(4201);" Client="Web" />
</ToolBar>
</Entity>

The text in Red is the same function called when you click new appointment from the menu. Save the changes  and refresh your contact form. 

Hope this helps
