Customise my wordpress blog

Tasks listed below. Task 1: Reduce the size and general presence of the sidebar plugin 'Recent Posts" Task 2: In 'Post Templates' in the new post section. (On the right) There is a 'Video Post Only' which I like, But I'd like a 'Full Width Video Post' also if you can do that. Task 3: When I publish a new post with a ‘featured image’ the picture shows up twice in the new post. Is there a way that we can stop this from happening. This is why I quite often use the ‘video only post’ custom template. Task 4: The general formatting of quotations/ heading (h1 to H5) and Dot Points are not satisfactory. They appear often to te far left or not correctly formatted. Can you please go through and correct all of this. I’d like the quotations to stand out in the posts better Centred, italic etc… the Dot points need to be aligned correctly and indented to the right. The heading need toi be formatted correctly. Task 5: Can we please create at 280 x 280 size advertisement place holder for the right hand sidebar (above Strava widget but below the search widget) I intend on getting advertising in here in the future. I’m not sure about the 280 x 280 but whatever fits in there. Task 6: The About Page – This page is formatted terribly and is an example of what I’m talking about in the above tasks. Can we fix this to make it look nicer. Can we also fix the format of ‘Pages’ so that all new pages look like the about page in their format.
