1.1.0

• Button now changes colour when pressed
• The purge function is run twice as many times as before, over a period of 5 seconds instead of all at once
• Update memory text more often as it seems to be less expensive and faster I expected it to be

1.0.0

• Created plugin

the PurgeMemory button does nothing when i click on it

the PurgeMemory button does nothing when i click on it

When clicked the button runs the function DiscordNative.processUtils.purgeMemory() a few times and prints a log in the console.
I have updated the plugin to give a visual indicator that the users input has been received.

The purge function itself does not immediately cause the ram usage to go down and seems to work better when pressed multiple times.
In addition to this, the tooltip text is only updated once every 2.5 seconds and must be hovered over again before the updated text will be displayed.

you should use https://openasar.dev/ and https://github.com/clachoverclan/DiscordRamLimit to have discord use the least amount of resources

Unfortunately, the ram limit program is not an option for users on operating systems other than windows and OpenAsar, while improving performance doesn't fix whatever memory leak my client has.

For anybody else in the future reading this, I strongly recommend auditing/verifying the validity of both programs and coming to your own conclusion on whether continued use of said programs (especially OpenAsar, which auto updates) are a worthwhile risk before using them.
