# Polymer – Quality of Life<\/p>\n
A client + server mod, which provides several quality of life improvements to players playing on servers powered
\nby PolyMc and polymer. The mod is
\nrequired to be installed on both the client and server to work!<\/p>\n
## Improvements<\/p>\n
### Client Side Mining<\/p>\n
If `client_mining` is enabled in the server config PolyMCs and polymers server side mining mechanics will be disabled
\nfor players with polymer-qol. The clients use polymers block syncing to figure out modded block breaking times to
\ncalculate them on the client. This allows for smoother block breaking *(especially useful on high ping)*.<\/p>\n
<\/p>\n
### No Block Updates<\/p>\n
When polymer-qol is installed on the client breaking and placing blocks won’t cause block updates on the client, which
\nremoves visually distracting incorrect blocks *(especially useful with high ping)*.<\/p>\n
<\/p>\n
### Preventing Arm Swing<\/p>\n
If `prevent_swing` is enabled in the server config, players with polymer-qol won’t swing their arms when interacting
\nwith fake noteblocks (which are often used for modded blocks).<\/p>\n
<\/p>\n
## Server Config<\/p>\n
The server config is located at `config\/polymer-qol-server.json` and allows server administrators to disable certain
\nfeatures.<\/p>\n
“`json
\n{
\n “_c0”: “Allows polymer-qol clients to perform block mining client-side”,
\n “client_mining”: true,
\n “_c1”: “Prevent polymer-qol clients from swinging their arm when interacting with fake noteblocks”,
\n “prevent_swing”: true
\n}
