The moment you click on any cell or line item That Filter pops up at the top right corner of the grid. You can squeeze the grid by changing the column settings.(It is really difficult when you have long time scales).
Probably you may want to put time in the page selectors if that works.
No unfortunately that icon is on the right. You can use quick filters as mentioned by T_Caban or you can published line items that you use as filter, so they look like a form on top of the module they filter
