[Feature Request] Ability to Turn Off Update Checking for Individual Plugins

[luxlogica]

While automatically checking - and updating - plugins is something we want 99% of the time, there are cases where it is not possible, or not advisable, for Sketch Plugin Manager to assist.

For instance, there are plugins that are not registered in the Sketch Plugins Directory, but which may nevertheless be popular - like the Craft plugins:

There are plugins that may more than one version. For instance, the Notebook plugin has a free version - which is what is listed in the Plugin Directory - but also a 'pro', commercial version - whose download address you receive only directly from the author, after paying your license fee. If, however, we instal the 'Pro' version of 'Notebook', Sketch Plugin Manager wrongly detects it as an 'older' version of the free plugin - and prompts me to update it, every time I launch Sketch.

Similarly, the very popular Auto-Layout plugin has been recently re-launched as Launchpad. Although they have the same feature set, the 'Auto-Layout' version is, unfortunately, buggy. Also unfortunately, if we download the 'Launchpad' version directly from the maker's website, and instal it, Sketch Plugin Manager detects it as being an 'older' version of 'Auto-Layout', and wants to "update" it every time we launch. If we "update" it, we'll end up with the buggy version:

While the situation with these particular plugins may be solved, there will always be new situations, with other plugins. It would, therefore, be incredibly useful if we could 'turn off' auto-checking for specific plugins, on a case-by-case basis.

Thank you for the suggestion, I'll consider including a solution in a future update.
