Keeping track of little objects can be a headache. If you're someone who is used to playing RTS games such as Warcraft III, then the same technique is used to create groups here. First, select the objects you want in your groups by drawing an enclosure using the brush tool. Press [ Ctrl] + [number] to add all the selected objects to that group. To select the group, press that number again.

Liquid Simulation Phun can do liquid simulations too. Liquids can't be created directly so you need to create shapes and then Solid objects need to be converted to create liquids convert them to liquids. So first draw the shapes like you normally would, then right click on the object and then click on Geometry settings > Liquify selected.

Some performance tweaks are necessary in CPU intensive simulations such as fluids
Tweaking Phun for Quality or Performance Phun simulates everything in real¬time so all the physics processing needs to be done in real-time by your processor. It's a heavy and strenuous task for the machine so a few settings can be altered when your scene becomes too complex to render smoothly. Click on Options under File and uncheck the box for Enable shaders and Draw clouds and check the one for Simple water rendering.

If your machine handles Phun perfectly fine, then by all means leave shaders and clouds on and turn off simple water rendering. If you're still left baffled by the things you can do with Phun, just load some ready made scenarios by clicking on File > Load Scene. You can then modif'y them or learn some new tricks from them
