🔎 Add searchbar for groups on the sidebar

Description:

• There are 2 boxes on the sidebar:
  • Group box on top (a box of groups/tags).
  • Settings box on bottom.
• When a user has a large number of groups, 2 things happen:
  • Settings box is far away on the bottom. You have to scroll all the group to get the settings.
  • It's very uncomfortable and slow to get a group.

Desired behaviour:

• Add a searchbar for groups on the top of this box. And maybe display only 5-10 groups by default.
• Maybe, change the order of the 2 boxes: settings on top and groups on bottom.
