This allows easier picker configuration for example:
```lua
require("telescope").setup {
pickers = {
buffers = {
show_all_buffers = true,
sort_lastused = true,
theme = "dropdown",
previewer = false,
mappings = {
i = {
["<c-q>"] = "smart_send_to_qflist",
}
}
}
}
}
```
This configuration will be applied when running `:Telescope buffers`
