I find it really gets in the way of using Zoho that to get to calendar view I have 3 clicks. Timesheet - All timesheet - Calendar View. This page should be right under dashboard on the Left menu given how integral it is to the use of the app, so I can bounce to it constantly.
Not being able to set calendar view as a default is frustrating.
***The fact that you show tasks instead of Projects in the default view of all entries has not been thought through. At a glance I want to see what PROJECTS I worked on most through the month/weeks and seeing tasks when I hover or click on the entry would make so much more sense. This page is everything. Why did you bury it? It should also be more customizable - filters / colours by project .. won't work for everyone's application but people could organize a few colours to suit their own organization needs/style.
