Random Place lets you place a weighted mix of blocks instead of only the one in your hand.
Open your inventory and press TB, next to the recipe book. Click blocks from your inventory to add them. Drag each bar to set how often that block is placed. Two bars in the same place means each one places half the time. A bar pulled to zero never places. On and Off keep the list but stop the random placing.
While it is on, placing a block uses one of the selected blocks. The block is taken from your inventory first, then from a Sophisticated Backpack, including a backpack you are wearing and backpacks stored inside another backpack. Right-clicking a chest or a machine still opens it.
Install the mod on the client and on the server. Players who want the TB button need it in their own mods folder.
