Fix folders not opening (#162)

* chore: Major refactoring

Still needs a massive go-over because there shouldn't be anything referencing tauri in any of the workspaces except the original one. Process manager has been refactored as an example

-# Drop App
+# Drop Desktop Client
 
-Drop app is the companion app for [Drop](https://github.com/Drop-OSS/drop). It uses a Tauri base with Nuxt 3 + TailwindCSS on top of it, so we can re-use components from the web UI.
+The Drop Desktop Client is the companion app for [Drop](https://github.com/Drop-OSS/drop). It is the official & intended way to download and play games on your Drop server.
 
-## Running
+## Internals
-Before setting up the drop app, be sure that you have a server set up. 
-The instructions for this can be found on the [Drop Docs](https://docs.droposs.org/docs/guides/quickstart)
 
-## Current features
+It uses a Tauri base with Nuxt 3 + TailwindCSS on top of it, so we can re-use components from the web UI.
-Currently supported are the following features:
-- Signin (with custom server)
-- Database registering & recovery
-- Dynamic library fetching from server
-- Installing & uninstalling games
-- Download progress monitoring
-- Launching / playing games
 
 ## Development
+Before setting up a development environemnt, be sure that you have a server set up. The instructions for this can be found on the [Drop Docs](https://docs.droposs.org/docs/guides/quickstart).
 
-Install dependencies with `yarn`
+Then, install dependencies with `yarn`. This'll install the custom builder's dependencies. Then, check everything works properly with `yarn tauri build`. 
 
-Run the app in development with `yarn tauri dev`. NVIDIA users on Linux, use shell script `./nvidia-prop-dev.sh`
+Run the app in development with `yarn tauri dev`. NVIDIA users on Linux, use shell script `./nvidia-prop-dev.sh`
 
 To manually specify the logging level, add the environment variable `RUST_LOG=[debug, info, warn, error]` to `yarn tauri dev`:
 
 e.g. `RUST_LOG=debug yarn tauri dev`
